Running existing tests

To run tests from an existing collection, first use configure as usual to set up the source directory containing the tests. Then try running

make check

If the check target exists, it usually saves you some trouble--for instance, it can set up any auxiliary programs or other files needed by the tests.

Once you have run `make check' to build any auxiliary files, you might want to call the test driver runtest directly to repeat the tests. You may also have to call runtest directly for test collections with no check target in the `Makefile'.

Typically, you must use two command-line options: `--tool', to specify which set of tests to run(1), and `--srcdir', to specify where to find test directories.

For example, if the directory `gdb/testsuite' contains a collection of DejaGnu tests for GDB, you can run them like this:

eg$ cd gdb/testsuite
eg$ runtest --tool gdb
Test output follows, ending with:

		=== gdb Summary ===

# of expected passes 508
# of expected failures 103
/usr/latest/bin/gdb version 4.14.4 -nx

You can use the option `--srcdir' to point to some other directory containing a collection of tests:

eg$ runtest --tool gdb --srcdir /devo/gdb/testsuite

These examples assume a native configuration, where the same computer runs both runtest and the tests themselves. When you have a cross configuration, the tests run on a different computer, controlled by the host running runtest. In this situation, you need the option `--name' to specify the network address for the other computer:

eg$ runtest --tool gdb --name vx9.munist.com

If you always use the same option values, you can record them in a file called `site.exp', rather than typing them each time. See section Config Variables.

By default, runtest prints only the names of the tests it runs, output from any tests that have unexpected results, and a summary showing how many tests passed and how many failed. To display output from all tests (whether or not they behave as expected), use the `--all' option. For more verbose output about processes being run, communication, and so on, use `--verbose'. To see even more output, use multiple `--verbose' options. See section Using runtest, for a more detailed explanation of each runtest option.

Test output goes into two files in your current directory: summary output in `tool.sum', and detailed output in `tool.log'. (tool refers to the collection of tests; for example, after a run with `--tool gdb', look for output files `gdb.sum' and `gdb.log'.) See section The files DejaGnu writes.
