class TestRegistrationClosedException extends StackDepthException

Exception that indicates an action that is only allowed during a suite's test registration phase, such as registering a test to run or ignore, was attempted after registration had already closed.

In suites that register tests as functions, such as FunSuite and FunSpec, tests are normally registered during construction. Although it is not the usual approach, tests can also be registered after construction by invoking methods that register tests on the already constructed suite so long as run has not been invoked on that suite. As soon as run is invoked for the first time, registration of tests is "closed," meaning that any further attempts to register a test will fail (and result in an instance of this exception class being thrown). This can happen, for example, if an attempt is made to nest tests, such as in a FunSuite:

test("this test is fine") {
  test("but this nested test is not allowed") {
  }
}

This exception encapsulates information about the stack depth at which the line of code that made this attempt resides, so that information can be presented to the user that makes it quick to find the problem line of code. (In other words, the user need not scan through the stack trace to find the correct filename and line number of the offending code.)

    A string that provides the filename of the line of code that failed, suitable for presenting to a user, which is taken from this exception's StackTraceElement at the depth specified by failedCodeStackDepth.

    This is a def instead of a val because exceptions are mutable: their stack trace can be changed after the exception is created. This is done, for example, by the SeveredStackTraces trait.

    returns

    A string that provides the filename and line number of the line of code that failed, suitable for presenting to a user of the failing line. It calls failedCodeFileName and failedCodeLineNumber to get the failing filename and line number.

    failedCodeFileName and failedCodeLineNumber will fall back to exception stack trace when Position is not avaiable, this is the reason it is a def instead of a val, because exceptions are mutable: their stack trace can be changed after the exception is created. This is done, for example, by the SeveredStackTraces trait.

    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.
