DUB-TEST(1) The D Language Foundation DUB-TEST(1)

NAME

dub-test - Executes the tests of the selected package

SYNOPSIS

dub test [<package>[@<version-spec>]] OPTIONS... [-- <application arguments...>]

DESCRIPTION

Builds the package and executes all contained unit tests.

If no explicit configuration is given, an existing "unittest" configuration will be preferred for testing. If none exists, the first library type configuration will be used, and if that doesn't exist either, the first executable configuration is chosen.

When a custom main file (--main-file) is specified, only library configurations can be used. Otherwise, depending on the type of the selected configuration, either an existing main file will be used (and needs to be properly adjusted to just run the unit tests for 'version(unittest)'), or DUB will generate one for library type configurations.

Finally, if the package contains a dependency to the "tested" package, the automatically generated main file will use it to run the unit tests.

OPTIONS

--temp-build

Builds the project in the temp folder if possible.

--main-file=VALUE

Specifies a custom file containing the main() function to use for running the tests.

--combined

Tries to build the whole project in a single compiler run.

--parallel

Runs multiple compiler instances in parallel, if possible.

-f, --force

Forces a recompilation even if the target is up to date

--coverage

Enables code coverage statistics to be generated.

--coverage-ctfe

Enables code coverage (including CTFE) statistics to be generated.

-b, --build=VALUE

Specifies the type of build to perform. Note that setting the DFLAGS environment variable will override the build type with custom flags. Possible names:
debug, plain, release, release-debug, release-nobounds, unittest, profile, profile-gc, docs, ddox, cov, cov-ctfe, unittest-cov, unittest-cov-ctfe, syntax and custom types

-c, --config=VALUE

Builds the specified configuration. Configurations can be defined in dub.json

--override-config=VALUE

Uses the specified configuration for a certain dependency. Can be specified multiple times. Format: --override-config=<dependency>/<config>

--compiler=VALUE

Specifies the compiler binary to use (can be a path). Arbitrary pre- and suffixes to the identifiers below are recognized (e.g. ldc2 or dmd-2.063) and matched to the proper compiler type:
dmd, gdc, ldc, gdmd, ldmd

-a, --arch=VALUE

Force a different architecture (e.g. x86 or x86_64)

-d, --debug=VALUE

Define the specified `debug` version identifier when building - can be used multiple times

--d-version=VALUE

Define the specified `version` identifier when building - can be used multiple times. Use sparingly, with great power comes great responsibility! For commonly used or combined versions and versions that dependees should be able to use, create configurations in your package.

--nodeps

Do not resolve missing dependencies before building

--build-mode=VALUE

Specifies the way the compiler and linker are invoked. Valid values:
separate (default), allAtOnce, singleFile

--single

Treats the package name as a filename. The file must contain a package recipe comment.

--force-remove

Deprecated option that does nothing.

--filter-versions

[Experimental] Filter version identifiers and debug version identifiers to improve build cache efficiency.
