Takes two positional + arguments, the first is the name of the test and the second is the + executable to run. The executable can be an [[@exe]] object returned by + [[executable]] or an [[@external_program]] object] returned by + [[find_program]]. + + *(since 0.55.0)* When cross compiling, if an exe_wrapper is needed and + defined the environment variable `MESON_EXE_WRAPPER` will be set to + the string value of that wrapper (implementation detail: using + `mesonlib.join_args`). Test scripts may use this to run cross built + binaries. If your test needs `MESON_EXE_WRAPPER` in cross build + situations it is your responsibility to return code 77 to tell the + harness to report "skip". + + By default, environment variable + [`MALLOC_PERTURB_`](http://man7.org/linux/man-pages/man3/mallopt.3.html) + is automatically set by `meson test` to a random value between 1..255. + This can help find memory leaks on configurations using glibc, + including with non-GCC compilers. However, this can have a performance + impact, and may fail a test due to external libraries whose internals + are out of the user's control. To check if this feature is causing an + expected runtime crash, disable the feature by temporarily setting + environment variable `MALLOC_PERTURB_=0`. While it's preferable to + only temporarily disable this check, if a project requires permanent + disabling of this check in meson.build do like: + + ```meson + nomalloc = environment({'MALLOC_PERTURB_': '0'}) + + test(..., env: nomalloc, ...) + ``` + + Defined tests can be run in a backend-agnostic way by calling + `meson test` inside the build dir, or by using backend-specific + commands, such as `ninja test` or `msbuild RUN_TESTS.vcxproj`. + +posargs_inherit: benchmark +kwargs_inherit: benchmark + +kwargs: + is_parallel: + type: bool + default: false + description: | + when false, specifies that no other test must be + running at the same time as this test |
