A language agnostic testing tool.

Create a test file <name>.

Call simple-test with one or more test files specified as command line arguments.

$ simple-test myscript.py yourscript.pl theirexecutable

By default, the test file itself will be executed, so you must make sure it is executable.

$ chmod +x myscript.py
$ cat myscript.py
#!/usr/bin/env python3
print("hello world!")

The default can be overriden by creating a <name>.cmd file, $filename will be substituted with with the actual filename.

$ cat myscript
print("hello world")

$ cat myscript.cmd
python $filename

By default, simple-test only tests that the exit code of the tested program will be non-zero. This can be overridden by providing a <name>.exit file which contains the expected exit code.

$ cat myscript.py
#!/usr/bin/env python3
import sys
sys.exit(100)

$ cat myscript.py.exit
100

The expected output of the program can be specified by providing the <name>.stdout and/or <name>.stderr files.

$ cat myscript.py
#!/usr/bin/env python3
print("hello world!")

$ cat myscript.py.stdout
hello world

Similarly, standard input which should be sent to the tested program can be provided with a <name>.stdin file.

$ cat myscript.py
#!/usr/bin/env python3
name = input()
print(f"hello {name}!")

$ cat myscript.py.stdin
dear friend

$ cat myscript.py.stdout
hello dear friend!

And that's it!
