For example, to run the memwipe tests in +isolation, you just run ./src/test/test-memwipe . + +To run tests within the unit test programs, you can specify the name +of the test. The string ".." can be used as a wildcard at the end of the +test name. For example, to run all the cell format tests, enter +"./src/test/test cellfmt/..". To run + +Many tests that need to mess with global state run in forked subprocesses in +order to keep from contaminating one another. But when debugging a failing test, +you might want to run it without forking a subprocess. To do so, use the +"--no-fork" option with a single test. (If you specify it along with +multiple tests, they might interfere.) + +You can turn on logging in the unit tests by passing one of "--debug", +"--info", "--notice", or "--warn". By default only errors are displayed. + +Unit tests are divided into "./src/test/test" and "./src/test/test-slow". +The former are those that should finish in a few seconds; the latter tend to +take more time, and may include CPU-intensive operations, deliberate delays, +and stuff like that. === Finding test coverage When you configure Tor with the --enable-coverage option, it should build with support for coverage in the unit tests, and in a special -"tor-cov" binary. If you launch +"tor-cov" binary. + +Then, run the tests you'd like to see coverage from. If you have old +coverage output, you may need to run "reset-gcov" first. + +Now you've got a bunch of files scattered around your build directories +called "*.gcda". In order to extract the coverage output from them, make a +temporary directory for them and run "./scripts/test/coverage ${TMPDIR}", +where ${TMPDIR} is the temporary directory you made. This will create a +".gcov" file for each source file under tests, containing that file's source +annotated with the number of times the tests hit each line. (You'll need to +have gcov installed.) + +You can get a summary of the test coverage for each file by running +"./scripts/test/cov-display ${TMPDIR}/*" . Each line lists the file's name, +the number of uncovered lines, the number of uncovered lines, and the +coverage percentage. + +For a summary of the test coverage for each _function_, run +"./scripts/test/cov-display -f ${TMPDIR}/*" . + +=== Comparing test coverage + +Sometimes it's useful to compare test coverage for a branch you're writing to +coverage from another branch (such as git master, for example). But you +can't run "diff" on the two coverage outputs directly, since the actual +number of times each line is executed aren't so important, and aren't wholly +deterministic. + +Instead, follow the instructions above for each branch, creating a separate +temporary directory for each. Then, run "./scripts/test/cov-diff ${D1} +${D2}", where D1 and D2 are the directories you want to compare. This will +produce a diff of the two directories, with all lines normalized to be either +covered or uncovered. + +To count new or modified uncovered lines in D2, you can run: + + "./scripts/test/cov-diff ${D1} ${D2}" | grep '^+ *\#' |wc -l -XXXX "make test-network" doesn't know about "tor-cov"; you don't get -XXXX coverage from that yet, unless you do "cp src/or/tor-cov -XXXX src/or/tor" before you run it.

(If not, please +consider refactoring it until most of it _is_ a good fit for unit +tests!) +If your code adds new externally visible functionality to Tor, it would +be great to have a test for that functionality.
