@hackage shelltestrunner0.6

Run a given program through "shell" tests specifed by one or more test files, where each test can specify: command-line arguments, input, expected output, expected stderr output, and/or expected exit code. This was extracted from the hledger project, inspired by the tests in John Wiegley's ledger project, and uses test-framework's test runner.

Usage:

shelltestrunner [opts] executable testfile1 [testfile2 ...] [-- <test-framework runner opts>]

You can pass options through to test-framework's runner; they must go after -- at the end. You may be able to get a big speedup by running tests in parallel: try -- -j8.

Test file format:

A test file contains 0 or more shell tests, each of which looks like this:

# 0 or more comment lines beginning with #
-opt1 -opt2 arg1 arg2 # one line of command line args, executable will be prepended
<<<
0 or more lines of input
>>> [/regexp/]
[..or 0 or more lines of expected output]
>>>2 [/regexp/]
[..or 0 or more lines of expected error output]
>>>= [expected numeric exit code or /regexp/]

Each expected field can have either a regular expression match expression, in which case the test passes if the output is matched, or 0 or more data lines, in which case the output must match these exactly. A ! preceding a /regexp/ negates the match. The regular expression syntax is that supported by the regexpr library.

Apart from the command line, all fields are optional. Only the fields you specify will be tested, unless you use the -i/--implicit-tests flag, which adds default tests (empty stdout, empty stderr, and 0 exit code) for omitted fields.

Issues:

• can't test input/output which does not end with newline

• can't use / in regexps

• option processing and --help output could be better

Wishlist:

• configurable delimiters
