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.

Returns an exception of class TestFailedException 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.)

Inherited methods
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
- Inherited from:
- StackDepth
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.
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.

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.
