let run-tests run optional code coverage tests.
to enable, set env var TEST_COVERAGE to non-empty string. run-tests will
print report after running.
after coverage run, file tests/.coverage will contain coverage data. use
tests/coverage.py to get more info, like annotated source code.
A simple testing framework
To run the tests, do:
cd tests/
./run-tests
This finds all scripts in the test directory named test-* and executes
them. The scripts can be either shell scripts or Python. Each test is
run in a temporary directory that is removed when the test is complete.
A test-<x> succeeds if the script returns success and its output
matches test-<x>.out. If the new output doesn't match, it is stored in
test-<x>.err.
There are some tricky points here that you should be aware of when
writing tests:
- hg commit and hg up -m want user interaction
for commit use -m "text"
for hg up -m, set HGMERGE to something noninteractive (like true or merge)
- changeset hashes will change based on user and date which make
things like hg history output change
use commit -m "test" -u test -d "1000000 0"
- diff will show the current time
use hg diff | sed "s/\(\(---\|+++\) [a-zA-Z0-9_/.-]*\).*/\1/" to strip
dates
