Properties

defaultStepTimeout → Duration
Returns the default timeout for the step. Steps that should respond quickly should use a relatively low value and steps that may take a long time should return an appropriately longer time. Defaults null which

Methods

execute({CancelToken cancelToken, TestReport report, TestController tester}) → Future<void>
Executes the test step by ensuring the Testable with the given id exists on the widget tree before continuing. This will throw an error is the Testable with the set testableId cannot be found on the tree before the timeout is exceeded.
override
log(String message, {TestController tester}) → void
Logs a message and posts it as a status update to the TestRunner.
@protected, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
postStepSleep(Duration duration) → Future<void>
Overidden to ignore the delay
override
preStepSleep(Duration duration) → Future<void>
Overidden to ignore the delay
override
sleep(Duration duration, {Stream<void> cancelStream, bool error = false, String message, TestController tester}) → Future<void>
Sleeps for the defined Duration. This accept an optional cancelStream which can be used to cancel the sleep. The error flag informs the sleeper about whether the duration is a standard duration or an error based timeout. [...]
@protected, inherited
toJson() → Map<String, dynamic>
Converts this to a JSON compatible map. For a description of the format, see fromDynamic.
override
toString() → String
Returns the string encoded JSON representation for this class. This will remove all null values and empty collections from the returned string.
inherited
waitFor(dynamic testableId, {CancelToken cancelToken, TestController tester, Duration timeout}) → Future<Finder>
Waits for a widget with a key that has testableId as the value.
