$ conan test [-h] [-tbf TEST_BUILD_FOLDER] [-b [BUILD]] [-e ENV] [-o OPTIONS] [-pr PROFILE] [-r REMOTE] [-s SETTINGS] [-u] path reference
Tests a package consuming it from a conanfile.py with a test() method.
This command installs the conanfile dependencies (including the tested package), calls a ‘conan build’ to build test apps and finally executes the test() method. The testing recipe does not require name or version, neither definition of package() or package_info() methods. The package to be tested must exist in the local cache or in any configured remote.
positional arguments: path Path to the "testing" folder containing a conanfile.py or to a recipe file with test() methode.g. conan test_package/conanfile.py pkg/version@user/channel reference pkg/version@user/channel of the package to be tested optional arguments: -h, --help show this help message and exit -tbf TEST_BUILD_FOLDER, --test-build-folder TEST_BUILD_FOLDER Working directory of the build process. -b [BUILD], --build [BUILD] Optional, use it to choose if you want to build from sources: --build Build all from sources, do not use binary packages. --build=never Never build, use binary packages or fail if a binary package is not found. --build=missing Build from code if a binary package is not found. --build=cascade Will build from code all the nodes with some dependency being built (for any reason). Can be used together with any other build policy. Useful to make sure that any new change introduced in a dependency is incorporated by building again the package. --build=outdated Build from code if the binary is not built with the current recipe or when missing binary package. --build=[pattern] Build always these packages from source, but never build the others. Allows multiple --build parameters. 'pattern' is a fnmatch file pattern of a package reference. Default behavior: If you don't specify anything, it will be similar to '--build=never', but package recipes can override it with their 'build_policy' attribute in the conanfile.py. -e ENV, --env ENV Environment variables that will be set during the package build, -e CXX=/usr/bin/clang++ -o OPTIONS, --options OPTIONS Define options values, e.g., -o Pkg:with_qt=true -pr PROFILE, --profile PROFILE Apply the specified profile to the install command -r REMOTE, --remote REMOTE Look in the specified remote server -s SETTINGS, --settings SETTINGS Settings to build the package, overwriting the defaults. e.g., -s compiler=gcc -u, --update Check updates exist from upstream remotes
This command is util for testing existing packages, that have been previously built (with conan create, for example). conan create will automatically run this test if a test_package folder is found besides the conanfile.py, or if the --test-folder argument is provided to conan create.
$ conan new Hello/0.1 -s -t $ mv test_package test_package2 $ conan create . user/testing # doesn't automatically run test, it has been renamed # now run test $ conan test test_package2 Hello/0.1@user/testing
The test package folder, could be elsewhere, or could be even applied to different versions of the package.
