selectedSuiteName ↔ String?
The currently selected test suite name.
read / write
sleep ← ProgressValue?
Informs the controller that a sleep status update has happened.
write-only
sleepStream → Stream<ProgressValue?>
Returns the stream that will fire updates as a test is sleeping / waiting.
read-only
state → TestControllerState
Returns the current state for the test controller.
read-only
status ← String
Informs the controller that a test status update has happened.
write-only
statusStream → Stream<String>
Returns the stream that will fire updates when a test status changes.
read-only
step ← ProgressValue?
Informs the controller that a test step update has happened.
write-only
stepStream → Stream<ProgressValue?>
Returns the stream that will fire updates when a test moves from step to step.
read-only
stopOnFirstFail → bool
Defines whether or not the framework should stop on the first failed step or keep going and executing subsequent steps.
final
testImageReader → TestImageReader
The image reader to read images for golden image comparisons.
final
variables → Map<String, dynamic>
Returns an unmodifiable map of all the currently set variables.
read-only

Methods

cancelRunningTests([Duration timeout = const Duration(minutes: 5)]) → Future<void>
Canceles any currently running test. The current step will be the last to execute, but this may still take a while as the current second could be a long running step. [...]
clearCustomRoutes() → void
Clears all the custom routes.
clearVariables() → void
Clears all the variables.
dispose() → void
Disposes the controller. Once disposed, a controller can not be reused.
execute({String? name, TestReport? report, bool reset = true, Duration? stepTimeout, required List<TestStep> steps, bool submitReport = true, String? suiteName, TestSuiteReport? testSuiteReport, Duration? testTimeout, required int version}) → Future<TestReport>
Executes a series of tests steps. This accepts the name of the test which may be null or empty. The reset defines if the controller should ask the application to perform a full reset before running or if it should attempt to run for the current state. [...]
executeStep({required CancelToken cancelToken, required TestReport report, required TestStep step, bool subStep = true}) → Future<bool>
Executes a single step and attaches the execution information to the testReport. The cancelToken allows the step to be cancelled. Whenever a step has a loop or a long running task, it should listen to the stream from the token or read the flag from the token.
executeTest({required Test test, TestReport? report}) → Future<TestReport>
Executes a single test. This will reset the application and submit the report. If the report is set it will be used, otherwise a net-new TestReport will be created and returned.
exportCurrentTest({bool clear = true, required BuildContext context}) → Future<bool>
Attempts to export the current test via the testWriter value. This will return true if and only if the current testWriter both returns true and no exceptions were thrown along the way. [...]
getVariable(String variableName) → dynamic
Returns the variable from the controller. This will first iterate through each VariableResolver given to the controller and will return the value from the first resolver that did not throw an UnknownVariableException. [...]
loadTests(BuildContext? context, {String? suiteName}) → Future<List<PendingTest>?>
Loads the list of tests from the assigned TestReader. This accepts the BuildContext to allow the reader to provide visual feedback to the user in case the load takes a while.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
registerCustomRoute(String display, PageRoute? route) → void
Registers a custom route with the framework. These routes will be displayed on the TestStepsDialog and TestStepsPage. The display is the string to display in a ListTile's title to trigger navigation to the route. If the route is null, this will remove any route registered to the display. If the display is already registered, it will be replaced with the new route
removeVariable({required String variableName}) → void
Removes the variable with the given variableName from the controller.
reset() → Future<void>
Requests the application to perform a reset.
resolveVariable(dynamic input) → dynamic
Resolves the given input with any potential variable on the controller. Variable values use the mustache format and must begin with {{ and end with }}. If the input is not marked as a variable or there is no variable with the matching key registered then the input will be return unaltered.
runPendingTests(List<PendingTest> tests, [Duration waitTimeout = _kSuiteStartTimeout]) → Future<TestSuiteReport>
Runs a series of tests. For full runs, this is more memory efficient as it will only load the tests as needed.
runTests(List<Test> tests, {Duration? stepTimeout, Duration waitTimeout = _kSuiteStartTimeout}) → Future<TestSuiteReport>
Runs a series of tests. This is useful for smaller numbers of in-memory tests but the runPendingTests should be prefered for full application runs or for CI/CD pipelines as that only loads the bare minimum data up front and then loads the full test data on an as needed basis.
screencap() → Future<Uint8List?>
Executes a screen capture for the application. As a note, depending on the device this may take several seconds. The screenshot call is fully async so this will wait until up to TestStepDelays.screenshot for the response. [...]
setVariable({required dynamic value, required String variableName}) → void
Sets the variable with the variableName to the value.
submitReport(TestReport report) → Future<bool>
Submits the test report through the TestReporter.
toBehaviorDrivenDescription(Test test) → String
toString() → String
A string representation of this object. [...]
inherited

Operators

operator ==(Object other) → bool
The equality operator. [...]
inherited

Static Methods

of(BuildContext context) → TestController?
Returns the TestController provided by the widget tree. This will never throw an exception but may return null if no controller is available on the widget tree.
