PropertyCheckFailedException

abstract class PropertyCheckFailedException(messageFun: StackDepthException => String, cause: Option[Throwable], posOrStackDepthFun: Either[Position, StackDepthException => Int], payload: Option[Any], val undecoratedMessage: String, val args: List[Any], optionalArgNames: Option[List[String]]) extends TestFailedException

Exception that indicates a property check failed.

Value parameters:
args

the argument values that caused the property check to fail.

cause

an optional cause, the Throwable that caused this PropertyCheckFailedException to be thrown.

messageFun

a function that returns a detail message (not optional) for this PropertyCheckFailedException.

optionalArgNames

an optional list of string names for the arguments.

payload

an optional payload, which ScalaTest will include in a resulting TestFailed event

posOrStackDepthFun

either a source position or a function that returns the depth in the stack trace of this exception at which the line of test code that failed resides.

undecoratedMessage

just a short message that has no redundancy with args, labels, etc. The regular "message" has everything in it.

Throws:
NullArgumentException

if any parameter is null or Some(null).

Concrete methods

def argNames: List[String]

A list of names for the arguments that caused the property check to fail.

A list of names for the arguments that caused the property check to fail.

If the optionalArgNames class parameter is defined, this method returns the List[String] contained in the Some. Otherwise, it returns a list that gives "arg0" for the zeroeth argument, "arg1" for the first argument, "arg2" for the second argument, and so on.

Indicates whether this object is equal to the passed object. If the passed object is a TestFailedException, equality requires equal message, cause, and failedCodeStackDepth fields, as well as equal return values of getStackTrace.

def failedCodeFileName: Option[String]

A string that provides the filename of the line of code that failed, suitable for presenting to a user, which is taken from this exception's StackTraceElement at the depth specified by failedCodeStackDepth.

A string that provides the filename of the line of code that failed, suitable for presenting to a user, which is taken from this exception's StackTraceElement at the depth specified by failedCodeStackDepth.

This is a def instead of a val because exceptions are mutable: their stack trace can be changed after the exception is created. This is done, for example, by the SeveredStackTraces trait.

Returns:

a string containing the filename that caused the failed test

Inherited from:
StackDepth

A string that provides the filename and line number of the line of code that failed, suitable for presenting to a user of the failing line. It calls failedCodeFileName and failedCodeLineNumber to get the failing filename and line number.

A string that provides the filename and line number of the line of code that failed, suitable for presenting to a user of the failing line. It calls failedCodeFileName and failedCodeLineNumber to get the failing filename and line number.

failedCodeFileName and failedCodeLineNumber will fall back to exception stack trace when Position is not avaiable, this is the reason it is a def instead of a val, because exceptions are mutable: their stack trace can be changed after the exception is created. This is done, for example, by the SeveredStackTraces trait.

Returns:

a user-presentable string containing the filename and line number that caused the failed test

def failedCodeLineNumber: Option[Int]

A string that provides the line number of the line of code that failed, suitable for presenting to a user, which is taken from this exception's StackTraceElement at the depth specified by failedCodeStackDepth.

lazy val failedCodeStackDepth: Int

The depth in the stack trace of this exception at which the line of test code that failed resides.

The depth in the stack trace of this exception at which the line of test code that failed resides.

One reason this is lazy is to delay any searching of the stack trace until it is actually needed. It will usually be needed, but not always. For example, exceptions thrown during a shrink phase of a failed property will often be StackDepthExceptions, but whose failedCodeStackDepth will never be used. Another reason is to remove the need to create a different exception before creating this one just for the purpose of searching through its stack trace for the proper stack depth. Still one more reason is to allow the message to contain information about the stack depth, such as the failed file name and line number.
