class TestFailedException extends StackDepthException with ModifiableMessage[TestFailedException] with PayloadField with ModifiablePayload[TestFailedException]

Exception that indicates a test failed.

One purpose of this exception is to encapsulate information about the stack depth at which the line of test code that failed resides, so that information can be presented to the user that makes it quick to find the failing line of test code. (In other words, the user need not scan through the stack trace to find the correct filename and line number of the failing test.)

Another purpose of this exception is to encapsulate a payload, an object to be included in a TestFailed event as its payload, so it can be consumed by a custom reporter that understands the payload. For example, tests could take a screen shot image of a GUI when a test fails, and include that as a payload. A custom reporter could listen for such payloads and display the screen shots to the user.

    The depth in the stack trace of this exception at which the line of test code that failed resides.

    The depth in the stack trace of this exception at which the line of test code that failed resides.

    One reason this is lazy is to delay any searching of the stack trace until it is actually needed. It will usually be needed, but not always. For example, exceptions thrown during a shrink phase of a failed property will often be StackDepthExceptions, but whose failedCodeStackDepth will never be used. Another reason is to remove the need to create a different exception before creating this one just for the purpose of searching through its stack trace for the proper stack depth. Still one more reason is to allow the message to contain information about the stack depth, such as the failed file name and line number.
