Waiting Verification

The new functionality is here to provide fluent waitings.

Usage

The usage is similar to Atata’s Should assertions. Just use WaitTo instead of Should:

Component.WaitTo.Equal("...")

Component.WaitTo.BeVisible()

Component.WaitTo.BeEnabled()

If a condition is not met during the waiting time, which is taken from AtataContext by default (AtataContext.Current.WaitingTimeout and AtataContext.Current.WaitingRetryInterval), then TimeoutException is thrown.

Expectation Verification

The new functionality is here to provide warnings. This functionality is similar to the meaning of “soft assertions” term.

If the test you are writing is quite complex and you need to do several assertions during the test flow without breaking the test with assertion exception when the first assertion fails, the expectation functionality is for the help.

Usage

The usage is similar to Atata’s Should assertions. Just use ExpectTo instead of Should:

Component.ExpectTo.Equal("...")

It doesn’t throw an exception on failure, but write the warning assertion result to the log and adds it to AtataContext.Current.PendingFailureAssertionResults collection. When on TearDown AtataContext.Current?.CleanUp() is invoked, after the actual cleaning it will throw aggregate assertion exception with all found ExpectTo errors. When using NUnit (AtataContextBuilder.UseNUnitWarningReportStrategy()), it will record every expectation failure as NUnit warning, which is similar. It is also absolutely valid to use expectations inside AggregateAssert sections.

Configuration

The following methods are added to AtataContextBuilder for configuring expectation verification functionality:

public AtataContextBuilder UseWarningReportStrategy(IWarningReportStrategy strategy);

public AtataContextBuilder UseNUnitWarningReportStrategy();

When using NUnit, it is available to invoke UseNUnitWarningReportStrategy() during AtataContext configuration in order to record warnings as NUnit’s built-in warnings. For other testing frameworks (xUnit, MSTest) the native Atata expectation functionality will work well by default.

Note that not all test runners support/recognize NUnit warnings (for example Visual Studio 2019 test explorer does not for now, while 2015 and 2017 do).

New FindByScriptAttribute

FindByScriptAttribute - specifies that a control should be found by specific script. The script should return an element or collection of elements. The script can also return null for the case when the element is not found. The scope element is passed to the script as an argument and can be used in the script as arguments[0].

Usage

Find in the Scope of Parent

[FindByScript("return arguments[0].querySelector('span.someclass')")]
public Control<_> SomeControl { get; private set; }

Find in the Scope of Whole Page

[FindByScript("return document.querySelector('input[type=radio][value=OptionA]')")]
public RadioButton<_> OptionA { get; private set; }

New UseAllNUnitFeatures Method

New method is added to AtataContextBuilder:

public AtataContextBuilder UseAllNUnitFeatures();

Enables all NUnit features for Atata. Executes the following methods:

  • UseNUnitTestName()
  • UseNUnitAssertionExceptionType()
  • UseNUnitAggregateAssertionStrategy()
  • UseNUnitWarningReportStrategy()
  • AddNUnitTestContextLogging()
  • LogNUnitError()
  • TakeScreenshotOnNUnitError()
