NAME

       cargo-test - Execute unit and integration tests of a package

SYNOPSIS

       cargo test [OPTIONS] [--] [<ARGS>...]

DESCRIPTION

       Execute all unit and integration tests of a local package.

       All of the trailing arguments are passed to the test binaries generated for filtering tests and generally
       providing  options configuring how they run.  For example, this will run all tests with the name 'foo' in
       their name:

              cargo test foo

       If the --package argument is given, then 'SPEC' is a package id specification which indicates which pack‐
       age should be tested.  If it is not given, then the current package is tested.  For more  information  on
       'SPEC' and its format, see the "cargo help pkgid" command.

       The  --jobs  argument  affects  the building of the test executable but does not affect how many jobs are
       used when running the tests.

       Compilation can be configured via the 'test' profile in the manifest.

       By default the rust test harness hides output from test execution to keep results readable.  Test  output
       can be recovered (e.g.  for debugging) by passing --nocapture to the test binaries:

              cargo test -- --nocapture
