Wiki regression testing
Regression testing[1] is the way of testing (translating) a lot of "test phrases" and compare the result to the expected output. This is very useful if you want to change a rule or word and want to get an overview of the consequences. Along with testvoc it is a good way to test that your translator works, and that your changes haven't broken anything.
The regressions tests work by downloading a wiki page with the phrases and the expected output like the page English_and_Esperanto/Regression_tests and then running the translator.
Installation and invocation
You could simply copy the script regression-tests.sh from an existing language pair and change the names in it.
To start, type sh regression-tests.sh on a Unix box.
- Troubleshooting
If you get output like: regression-tests.sh: 28: [[: not found then try bash regression-tests.sh or make the script executable (chmod a+x regression-tests.sh) and execute it by ./regression-tests.sh .
Output
For each test, the scipt prints 1) source language 2) expected (correct) output 3) actual output from Apertium. In some test scripts it will only print out the "failed" test (where the expected and actual output is diverging), and in other test scripts it will print out all of the tests, and a summary.
