AbstractDateAssert (AssertJ fluent assertions 1.6.0 API)

java.lang.Object
- org.assertj.core.api.AbstractAssert<S,Date>
- - org.assertj.core.api.AbstractDateAssert<S>

Type Parameters:
S - the "self" type of this assertion class. Please read "Emulating 'self types' using Java Generics to simplify fluent API implementation" for more details.

All Implemented Interfaces:

Assert<S,Date>, Descriptable<S>, ExtensionPoints<S,Date>

Direct Known Subclasses:

DateAssert
```
public abstract class AbstractDateAssert<S extends AbstractDateAssert<S>>
extends AbstractAssert<S,Date>
```
Base class for all implementations of assertions for Dates.
Note that assertions with date parameter comes with two flavor, one is obviously a Date and the other is a String representing a Date.
For the latter, the default format follows ISO 8901 : "yyyy-MM-dd", user can override it with a custom format by calling withDateFormat(DateFormat).
The user custom format will then be used for all next Date assertions (i.e not limited to the current assertion) in the test suite.
To turn back to default format, simply call withDefaultDateFormatsOnly().

```
public S isInSameDayAs(String dateAsString)
```
    Same assertion as isInSameDayAs(Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.

 Date date2 = parseDatetime("2003-04-26T14:00:00");
 assertThat(date1).isInSameHourWindowAs(date2)
 
```
    Two dates can have different hour fields and yet be in the same chronological hour, example:
```
 Date date1 = parseDatetime("2003-04-26T13:00:00");
 Date date2 = parseDatetime("2003-04-26T12:59:59");
 // succeeds as time difference == 1s
 assertThat(date1).isInSameHourWindowAs(date2)
 
```
    This assertion fails as time difference is more than one hour:
```
 Date date1 = parseDatetime("2003-04-26T13:00:00");
 Date date2 = parseDatetime("2003-04-26T14:00:01");
 assertThat(date1).isInSameHourWindowAs(date2)
 
```
    To compare date's hour fields only (without day, month and year), you can write :
```
 assertThat(myDate).isWithinHour(hourOfDayOf(otherDate))
 
```
    see hourOfDayOf to get the hour of a given Date.
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator)).
    Parameters:
    other - the given Date to compare actual Date to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same hour.
  - isInSameHourWindowAs
```
public S isInSameHourWindowAs(String dateAsString)
```
    Same assertion as isInSameHourWindowAs(java.util.Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd
    Example of valid string date representations:
    - 2003-04-26T03:01:02.999
    - 2003-04-26T13:01:02
    - 2003-04-26
    Parameters:
    dateAsString - the given Date represented as String in default or custom date format.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if dateAsString parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same day of month.
  - isInSameHourAs
```
public S isInSameHourAs(Date other)
```
    Verifies that actual and given Date have same hour, day, month and year fields values.
    Example:
```
 Date date1 = parseDatetime("2003-01-01T12:00:00");
 Date date2 = parseDatetime("2003-01-01T12:30:00");

 // succeeds
 assertThat(date1).isInSameHourAs(date2);
 
```
    This assertion does not make a true chronological comparison since two dates can have different hour fields and yet be in the same chronological hour, e.g:
```
 // dates in the same hour time window but with different hour fields
 Date date1 = parseDatetime("2003-01-01T12:00:00");
 Date date2 = parseDatetime("2003-01-01T11:59:00");
 
```
    If you want to assert that two dates are chronologically in the same hour time window use isInSameHourWindowAs assertion (note that if isInSameHourAs succeeds then isInSameHourWindowAs will succeed too).
    If you want to compare hour only (without day, month and year), you could write : assertThat(myDate).isWithinHour(hourOfDayOf(otherDate))
    see Dates.hourOfDayOf(Date) to get the hour of a given Date.
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator).
    Parameters:
    other - the given Date to compare actual Date to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same hour.
  - isInSameHourAs
```
public S isInSameHourAs(String dateAsString)
```
    Same assertion as isInSameHourAs(Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd
    Example of valid string date representations:
    - 2003-04-26T03:01:02.999
    - 2003-04-26T13:01:02
    - 2003-04-26
    Parameters:
    dateAsString - the given Date represented as String in default or custom date format.
    
    Returns:
    this assertion object.

public S isInSameMinuteWindowAs(Date other)
```
    Verifies that actual and given Date are chronologically in the same hour (i.e. their time difference <= 1 hour).
    Example:
```
 Date date1 = parseDatetime("2003-01-01T12:01:00");
 Date date2 = parseDatetime("2003-01-01T12:01:30");

 // succeeds because date time difference < 1 min
 assertThat(date1).isInSameMinuteWindowAs(date2);
 
```
    Two dates can have different minute fields and yet be in the same chronological minute, example:
```
 Date date1 = parseDatetime("2003-01-01T12:01:00");
 Date date3 = parseDatetime("2003-01-01T12:00:59");

 // succeeds as time difference == 1s even though minutes fields differ
 assertThat(date1).isInSameMinuteWindowAs(date3)
 
```
    This assertion fails as time difference is >= one minute:
```
 Date date1 = parseDatetime("2003-01-01T12:01:00");
 Date date2 = parseDatetime("2003-01-01T12:02:00");

 // fails, time difference should hae been < 1 min
 assertThat(date1).isInSameMinuteWindowAs(date2); // ERROR
 
```
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator)).
    Parameters:
    other - the given Date to compare actual Date to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same minute.
  - isInSameMinuteWindowAs
```
public S isInSameMinuteWindowAs(String dateAsString)
```
    Same assertion as isInSameMinuteWindowAs(Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd
    Example of valid string date representations:
    - 2003-04-26T03:01:02.999
    - 2003-04-26T13:01:02
    - 2003-04-26
    Parameters:
    dateAsString - the given Date represented as String in default or custom date format.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if dateAsString parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same minute.
  - isInSameMinuteAs
```
public S isInSameMinuteAs(Date other)
```
    Verifies that actual and given Date have same minute, same hour, day, month and year fields values.
    Example:
```
 Date date1 = parseDatetime("2003-01-01T12:01:00");
 Date date2 = parseDatetime("2003-01-01T12:01:30");

 // succeeds because the all the fields up to minutes are the same
 assertThat(date1).isInSameMinuteAs(date2);
 
```
    It does not make a true chronological comparison since two dates can have different minute fields and yet be in the same chronological minute, e.g:
```
 // dates in the same minute time window but with different minute fields
 Date date1 = parseDatetime("2003-01-01T12:01:00");
 Date date3 = parseDatetime("2003-01-01T12:00:59");

 // fails because minutes fields differ even though time difference is only 1s !
 assertThat(date1).isInSameMinuteAs(date3); // ERROR
 
```
    If you want to assert that two dates are in the same minute time window use isInSameMinuteWindowAs assertion (note that if isInSameMinuteAs succeeds then isInSameMinuteWindowAs will succeed too).
    If you want to compare minute field only (without hour, day, month and year), you could write : assertThat(myDate).isWithinMinute(minuteOf(otherDate))
    using Dates.minuteOf(Date) to get the minute of a given Date.
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator)).
    Parameters:
    other - the given Date to compare actual Date to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same minute.
  - isInSameMinuteAs
```
public S isInSameMinuteAs(String dateAsString)
```
    Same assertion as isInSameMinuteAs(Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd
    Example of valid string date representations:
    - 2003-04-26T03:01:02.999
    - 2003-04-26T13:01:02
    - 2003-04-26
    Parameters:
    dateAsString - the given Date represented as String in default or custom date format.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if dateAsString parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same minute.
  - isInSameSecondWindowAs
```
public S isInSameSecondWindowAs(Date other)
```
    Verifies that actual and given Date are chronologically strictly in the same second (i.e. their time difference < 1 second).
    Example:
```
 Date date1 = parseDatetimeWithMs("2003-04-26T13:01:02.123");
 Date date2 = parseDatetimeWithMs("2003-04-26T13:01:02.456");

 // succeeds as time difference is < 1s
 assertThat(date1).isInSameSecondWindowAs(date2);
 
```
    Two dates can have different second fields and yet be in the same chronological second, example:
```
 Date date1 = parseDatetimeWithMs("2003-04-26T13:01:02.999");
 Date date2 = parseDatetimeWithMs("2003-04-26T13:01:03.000");

 // succeeds as time difference is 1ms < 1s
 assertThat(date1).isInSameSecondWindowAs(date2);
 
```
    Those assertions fail as time difference is greater or equal to one second:
```
 Date date1 = parseDatetimeWithMs("2003-04-26T13:01:01.000");
 Date date2 = parseDatetimeWithMs("2003-04-26T13:01:02.000");

 // fails as time difference = 1s
 assertThat(date1).isInSameSecondWindowAs(date2); // ERROR

 Date date3 = parseDatetimeWithMs("2003-04-26T13:01:02.001");
 // fails as time difference > 1s
 assertThat(date1).isInSameSecondWindowAs(date3); // ERROR
 
```
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator).
    Parameters:
    other - the given Date to compare actual Date to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same second.
  - isInSameSecondWindowAs
```
public S isInSameSecondWindowAs(String dateAsString)
```
    Same assertion as isInSameSecondWindowAs(Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd

    - 2003-04-26T13:01:02
    - 2003-04-26
    Parameters:
    dateAsString - the given Date represented as String.
    
    Throws:
    
    NullPointerException - if dateAsString parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if actual and given Date are not in the same second.
  - isInSameSecondAs
```
public S isInSameSecondAs(Date other)
```
    Verifies that actual and given Date have same second, minute, hour, day, month and year fields values.
```
 Date date1 = parseDatetimeWithMs("2003-01-01T12:00:01.000");
 Date date2 = parseDatetimeWithMs("2003-01-01T12:00:01.250");

 // succeeds because the all the time fields up to seconds are the same
 assertThat(date1).isInSameSecondAs(date2);
 
```
    It does not make a true chronological comparison since two dates can have different second fields and yet be in the same chronological second, e.g:
```
 Date date1 = parseDatetimeWithMs("2003-01-01T12:00:01.000");
 Date date3 = parseDatetimeWithMs("2003-01-01T12:00:00.999");

 // fails because seconds fields differ even though time difference is only 1ms !
 assertThat(date1).isInSameSecondAs(date3); // ERROR
 
```
    If you want to assert that two dates are in the same second time window use isInSameSecondWindowAs assertion.
    If you want to compare second fields only (without minute, hour, day, month and year), you could write : assertThat(myDate).isWithinSecond(secondOf(otherDate))
    using Dates.secondOf(Date) to get the second of a given Date.
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator)).
    Parameters:
    other - the given Date to compare actual Date to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.

    AssertionError - if actual and given Date are not in the same second.
  - isInSameSecondAs
```
public S isInSameSecondAs(String dateAsString)
```
    Same assertion as isInSameSecondAs(Date) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :

    - 2003-04-26
  - isCloseTo
```
public S isCloseTo(Date other,
          long deltaInMilliseconds)
```
    Verifies that the actual Date is close to the other date by less than delta (expressed in milliseconds), if difference is equals to delta it's ok.
    One can use handy TimeUnit to convert a duration in milliseconds, for example you can express a delta of 5 seconds with TimeUnit.SECONDS.toMillis(5).
    Note that using a custom comparator has no effect on this assertion (see usingComparator(Comparator).
    Example:
```
 Date date1 = new Date();
 Date date2 = new Date(date1.getTime() + 100);

 // assertion will pass
 assertThat(date1).isCloseTo(date2, 80);
 assertThat(date1).isCloseTo(date2, 100);

 // assertion will fail
 assertThat(date1).isCloseTo(date2, 101);
 
```
    Parameters:
    other - the date to compare actual to
    deltaInMilliseconds - the delta used for date comparison, expressed in milliseconds
    
    Returns:
    this assertion object.
    
    Throws:
    
    NullPointerException - if Date parameter is null.
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if the actual Date week is not close to the given date by less than delta.
  - isCloseTo
```
public S isCloseTo(String dateAsString,
          long deltaInMilliseconds)
```
    Same assertion as isCloseTo(Date, long) but given date is represented as String either with one of the supported defaults date format or a user custom date format (set with method withDateFormat(DateFormat)).
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format (expressed in the local time zone) are :
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd

```
 assertThat(new Date(42)).hasTime(42);
 
```
    Parameters:
    timestamp - the timestamp to compare actual time to.
    
    Returns:
    this assertion object.
    
    Throws:
    
    AssertionError - if the actual Date is null.
    
    AssertionError - if the actual Date time is not equal to the given timestamp.

  - withDateFormat
```
public S withDateFormat(DateFormat userCustomDateFormat)
```
    Instead of using default date formats for the date String based Date assertions like isEqualTo(String), AssertJ is gonna use any date formats registered with one of these methods :
    Beware that :
    - this will be the case for all future Date assertions in the test suite
    - once a custom date format is registered, the default date formats are not used anymore
    To revert to default format, call useDefaultDateFormatsOnly() or withDefaultDateFormatsOnly().
    Parameters:
    userCustomDateFormat - the new Date format used for String based Date assertions.
    
    Returns:
    this assertion object.
  - withDateFormat
```
public S withDateFormat(String userCustomDateFormatPattern)
```
    Instead of using default date formats for the date String based Date assertions like isEqualTo(String), AssertJ is gonna use any date formats registered with one of these methods :

    Parameters:
    userCustomDateFormatPattern - the new Date format string pattern used for String based Date assertions.
    
    Returns:

  - registerCustomDateFormat
```
public static void registerCustomDateFormat(DateFormat userCustomDateFormat)
```
    Add the given date format to the ones used to parse date String in String based Date assertions like isEqualTo(String).
    User date formats are used before default ones in the order they have been registered (first registered, first used).
    AssertJ is gonna use any date formats registered with one of these methods :
    - withDateFormat(String)
    - withDateFormat(java.text.DateFormat)
    - this method
    - registerCustomDateFormat(String)
    Beware that AssertJ will use the newly registered format for all remaining Date assertions in the test suite
    To revert to default formats only, call useDefaultDateFormatsOnly() or withDefaultDateFormatsOnly().
    Code examples:
```
 Date date = ... // set to 2003 April the 26th
 assertThat(date).isEqualTo("2003-04-26");

 try {
   // date with a custom format : failure since the default formats don't match.

 }

 // registering a custom date format to make the assertion pass
 registerCustomDateFormat(new SimpleDateFormat("yyyy/MM/dd")); // registerCustomDateFormat("yyyy/MM/dd") would work to.

  - usingComparator
```
public S usingComparator(Comparator<? super Date> customComparator)
```
    Description copied from class: AbstractAssert
    Use given custom comparator instead of relying on actual type A equals method for incoming assertion checks.
    Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.
    Examples :
```
 // frodo and sam are instances of Character with Hobbit race (obviously :).
 // raceComparator implements Comparator<Character> 
 assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam); 
 
```
    Specified by:
    
    usingComparator in interface Assert<S extends AbstractDateAssert<S>,Date>
    
    Overrides:
    
    usingComparator in class AbstractAssert<S extends AbstractDateAssert<S>,Date>
    
    Parameters:
    customComparator - the comparator to use for incoming assertion checks.
    
    Returns:
    this assertion object.
  - usingDefaultComparator
```
public S usingDefaultComparator()
```
    Description copied from class: AbstractAssert
    
    Revert to standard comparison for incoming assertion checks.
    This method should be used to disable a custom comparison strategy set by calling Assert.usingComparator(Comparator).
