TestStepDefinition

The test function that will be tested when this step is executed. The function can take an argument which will provide information about the current step's context.

The name of the step.

If truthy the current test step will be ignored.

This is a quick way to skip over a step, but also can be used for conditional logic, like determining if an environment feature is present.

Check that the number of async completed operations after the test step is the same as number of dispatched operations. This ensures that the code tested does not start async operations which it then does not await. This helps in preventing logic errors and memory leaks in the application code.

Defaults to the parent test or step's value.

Ensure the test step does not "leak" resources - like open files or network connections - by ensuring the open resources at the start of the step match the open resources at the end of the step.

Defaults to the parent test or step's value.

Ensure the test step does not prematurely cause the process to exit, for example via a call to Deno.exit.

Defaults to the parent test or step's value.
