getFormattedStacktrace {tinytest2JUnit}

Get formatted stack trace for an uncaught error from a tinytest test file.

Description

getFormattedStacktrace is a helper function that formats stacktrace for uncaught errors from a tinytest run file.

Usage

getFormattedStacktrace()

Details

This function assumes that it directly called from a withCallingHandler error handling function! This fact is then used to remove the calling handler info from the stack such that stack directly starts from where the error was thrown.

The function also removes the calls from the stack that involve executing the test_file. The internals of runTestDir and tinytest are not of intererst. And the highest level of the stack to consider is the top level of the test_file.

Note, this does mean that errors that occur on the top-level of the test file will not have a a stacktrace! For example: "Error: object 'x' not found" where x is attempted to be resolved at the root levels

Value

character(1) a single length character string suitable to be printed to the end-user. In case of no stakctrace (eg the error occured at root level of the script) NA_character_ is returned!
