DuplicateTestNameException

class DuplicateTestNameException extends StackDepthException

Exception that indicates an attempt was made to register a test that had the same name as a test already registered in the same suite. The purpose of this exception is to encapsulate 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.)

    Indicates whether this object is equal to the passed object. If the passed object is a DuplicateTestNameException, equality requires equal message, cause, and failedCodeStackDepth fields, as well as equal return values of getStackTrace.

  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

  12. def failedCodeFileNameAndLineNumberString: Option[String]

    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 user-presentable string containing the filename and line number that caused the failed test

  13. lazy val failedCodeFilePathname: Option[String]

    A string that provides the full pathname of the source file containing the line of code that failed, suitable for presenting to a user.

    A string that provides the full pathname of the source file containing the line of code that failed, suitable for presenting to a user.

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

    returns

    StackDepth
  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.
