StackDepthException

abstract class StackDepthException extends RuntimeException with StackDepth

Exception class that encapsulates information about the stack depth at which the line of code that failed resides, so that information can be presented to the user that makes it quick to find the failing 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 problem code.) Having a stack depth is more useful in a testing environment in which test failures are implemented as thrown exceptions, as is the case in ScalaTest's built-in suite traits.

Abstract Value Members

  1. abstract def severedAtStackDepth: Throwable with StackDepth

    Returns an exception of the same class with failedExceptionStackDepth set to 0 and all frames above this stack depth severed off.

    Returns an exception of the same class with failedExceptionStackDepth set to 0 and all frames above this stack depth severed off. This can be useful when working with tools (such as IDEs) that do not directly support ScalaTest. (Tools that directly support ScalaTest can use the stack depth information delivered in the StackDepth exceptions.)

  11. def failedCodeFileName: Option[String]

    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.

    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 containing the filename that caused the failed test

    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.

    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.

    returns

    A string that provides the line number 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.

  16. lazy val failedCodeStackDepth: Int

    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.
