Describe a “subject” being specified and tested by the passed function value.
Describe a “subject” being specified and tested by the passed function value. The
passed function value may contain more describers (defined with describe
) and/or tests
(defined with it
). This trait's implementation of this method will register the
description string and immediately invoke the passed function.
Register a test to ignore, which has the given spec text, optional tags, and test function value that takes no arguments.
Register a test to ignore, which has the given spec text, optional tags, and test function value that takes no arguments.
This method will register the test for later ignoring via an invocation of one of the execute
methods. This method exists to make it easy to ignore an existing test by changing the call to it
to ignore
without deleting or commenting out the actual test code. The test will not be executed, but a
report will be sent that indicates the test was ignored. The name of the test will be a concatenation of the text of all surrounding describers,
from outside in, and the passed spec text, with one space placed between each item. (See the documenation
for testNames
for an example.) The resulting test name must not have been registered previously on
this FeatureSpec
instance.

Run a test.
Run a test. This trait's implementation runs the test registered with the name specified by
testName
. Each test's name is a concatenation of the text of all describers surrounding a test,
from outside in, and the test's spec text, with one space placed between each item. (See the documenation
for testNames
for an example.)

This method takes a testName
parameter that optionally specifies a test to invoke.
If testName
is Some
, this trait's implementation of this method
invokes runTest

testName

value of the testName

- the Stopper

- the configMap

of tag names that should be included (tagsToInclude
), and a Set
that should be excluded (tagsToExclude
), when deciding which of this Suite
's tests to execute.
If tagsToInclude
is empty, all tests will be executed
except those those belonging to tags listed in the tagsToExclude
Set
. If tagsToInclude
is non-empty, only tests
belonging to tags mentioned in tagsToInclude
, and not mentioned in tagsToExclude
will be executed. However, if testName
is Some
, tagsToInclude
and tagsToExclude
are essentially ignored.
Only if testName
is None
will tagsToInclude
and tagsToExclude
be consulted to
determine which of the tests named in the testNames
Set
should be run. For more information on trait tags, see the main documentation for this trait.
If testName
is None
, this trait's implementation of this method
invokes testNames
on this Suite
to get a Set
of names of tests to potentially execute.
(A testNames
value of None
essentially acts as a wildcard that means all tests in
this Suite
that are selected by tagsToInclude
and tagsToExclude
should be executed.)
For each test in the testName
Set
, in the order
they appear in the iterator obtained by invoking the elements
method on the Set
, this trait's implementation
of this method checks whether the test should be run based on the tagsToInclude
and tagsToExclude
Set
s.
If so, this implementation invokes runTest
, passing in:
testName
- the String
name of the test to run (which will be one of the names in the testNames
Set
)reporter

- the configMap

, all relevant tests should be run.

Registers shared scenarios.
Registers shared scenarios.
This method enables the following syntax for shared scenarios in a FeatureSpec
:
scenariosFor(nonEmptyStack(lastValuePushed))
This method just provides syntax sugar intended to make the intent of the code clearer.
Because the parameter passed to it is
type Unit
, the expression will be evaluated before being passed, which
is sufficient to register the shared scenarios. For examples of shared scenarios, see the
Shared scenarios section in the main documentation for this trait.

A Map

A Map
whose keys are String
names of tagged tests and whose associated values are
the Set
of tag names for the test. If this FeatureSpec
contains no tags, this method returns an empty Map
.
This trait's implementation returns tags that were passed as strings contained in Tag
objects passed to
methods scenario
and ignore
.
In addition, this trait's implementation will also auto-tag tests with class level annotations.
For example, if you annotate @Ignore
at the class level, all test methods in the class will be auto-annotated with
org.scalatest.Ignore
.
An immutable Set
of test names.
An immutable Set
of test names. If this FeatureSpec
contains no tests, this method returns an
empty Set
.
This trait's implementation of this method will return a set that contains the names of all registered tests. The set's
iterator will return those names in the order in which the tests were registered. Each test's name is composed
of the concatenation of the text of each surrounding describer, in order from outside in, and the text of the
example itself, with all components separated by a space. For example, consider this FeatureSpec
:
import org.scalatest.FeatureSpec class StackSpec extends FeatureSpec { feature("A Stack") { scenario("(when not empty) must allow me to pop") {} scenario("(when not full) must allow me to push") {} } }
Invoking testNames
on this FeatureSpec
will yield a set that contains the following
two test name strings:
"A Stack (when not empty) must allow me to pop" "A Stack (when not full) must allow me to push"
Implementation trait for class
FeatureSpec
, which represents a suite of tests in which each test represents one scenario of a feature.FeatureSpec
is a class, not a trait, to minimize compile time given there is a slight compiler overhead to mixing in traits compared to extending classes. If you need to mix the behavior ofFeatureSpec
into some other class, you can use this trait instead, because classFeatureSpec
does nothing more than extend this trait and add a nicetoString
implementation.See the documentation of the class for a detailed overview of
FeatureSpec
.
