.TH DUB-TEST 1 "2024-07-07" "The D Language Foundation" "The D Language Foundation"
.SH NAME
dub-test \- Executes the tests of the selected package
.SH SYNOPSIS
\fBdub test \fR[<\fIpackage\fR>[@<\fIversion-spec\fR>]] \fIOPTIONS\&.\&.\&.\fR
[-- <\fIapplication arguments\&.\&.\&.\fR>]
.SH 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.

.RE
.PP
\fB\-b\fR, \fB\-\-build\fR=\fIVALUE\fR
.RS 4
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
.RE
.PP
\fB\-c\fR, \fB\-\-config\fR=\fIVALUE\fR
.RS 4
Builds the specified configuration. Configurations can be defined in dub.json
.RE
.PP
\fB\-\-override\-config\fR=\fIVALUE\fR
.RS 4
Uses the specified configuration for a certain dependency. Can be specified multiple times.
Format: --override-config=<dependency>/<config>
.RE
.PP
\fB\-\-compiler\fR=\fIVALUE\fR
.RS 4
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
.RE
.PP
\fB\-a\fR, \fB\-\-arch\fR=\fIVALUE\fR
.RS 4
Force a different architecture (e.g. x86 or x86_64)
.RE
.PP
\fB\-d\fR, \fB\-\-debug\fR=\fIVALUE\fR
.RS 4
Define the specified `debug` version identifier when building - can be used multiple times
.RE
.PP
\fB\-\-d\-version\fR=\fIVALUE\fR
.RS 4
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.
.RE
.PP
\fB\-\-nodeps\fR
.RS 4
Do not resolve missing dependencies before building
.RE
.PP
\fB\-\-build\-mode\fR=\fIVALUE\fR

.RS 4
Deprecated option that does nothing.
.RE
.PP
\fB\-\-filter\-versions\fR
.RS 4
