.SH NAME
.PP
cargo\-test \- Execute unit and integration tests of a package
.SH SYNOPSIS
.PP
\f[I]cargo test\f[] [OPTIONS] [\-\-] [<ARGS>...]
.SH DESCRIPTION
.PP
Execute all unit and integration tests of a local package.
.PP
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 \[aq]foo\[aq] in
their name:
.IP
.nf
\f[C]
cargo\ test\ foo
\f[]
.fi
.PP
If the \f[B]\-\-package\f[] argument is given, then \[aq]SPEC\[aq] is a
package id specification which indicates which package should be tested.
If it is not given, then the current package is tested.
For more information on \[aq]SPEC\[aq] and its format, see the "cargo
help pkgid" command.
.PP
The \f[B]\-\-jobs\f[] argument affects the building of the test
executable but does not affect how many jobs are used when running the
tests.
.PP
Compilation can be configured via the \[aq]test\[aq] profile in the
manifest.
.PP
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 \f[B]\-\-nocapture\f[] to the test binaries:
.IP
.nf
\f[C]
cargo\ test\ \-\-\ \-\-nocapture
\f[]
.fi
