Unit testing: Difference between revisions

Jsish supports an '''internal''' ''-u'' command line option to run unit tests, as part of the base implementation. These tests can include trial inputs and expected outputs in special comment blocks within a source file. Other command line options determine the level of verbosity and logging used when running tests. Being inside comment sections, unit tests do not affect the normal operation of a script (besides the negligible time taken for the interpreter to read in and skip over the comment sections). When in ''-u'' test-mode, source lines starting and ending with semi-colons '';'' are echoed using a special output format that also evaluates the enclosed expression and captures the result.

 

var line = console.input();

var nums = line.match(/^\s*([+-]?[0-9]+)\s+([+-]?[0-9]+)\s*/);

Typical test cases look like:

self should:[ 0 ln ] raise:DomainError.

self should:[ 0 log2 ] raise:DomainError.

n := sqrt := nil.

 

 

When executed headless, a result object is returned from a run, which can be printed or further analyzed.

outcome printCR.
