KYUAFILE(5) FreeBSD File Formats Manual KYUAFILE(5) NAME Kyuafile - Test suite description files SYNOPSIS atf_test_program(string name, [string test_suite], [string metadata]); include(string path); plain_test_program(string name, [string test_suite], [string metadata]); syntax(int version); test_suite(string name); DESCRIPTION A test suite is a collection of test programs and is represented by a hierarchical layout of test binaries on the file system. Any subtree of the file system can represent a test suite, provided that it includes one or more Kyuafiles, which are the test suite definition files. A Kyuafile is a Lua script whose purpose is to describe the structure of the test suite it belongs to. To do so, the script has access to a collection of special functions provided by kyua(1). A typical Kyuafile will look similar to this: syntax(2) test_suite('first') -- Declare the test programs that are in this directory. atf_test_program{name='foo_test'} atf_test_program{name='bar_test', test_suite='second'} plain_test_program{name='legacy_test'} plain_test_program{name='legacy2_test', allowed_architectures='amd64 i386', required_files='/bin/ls', timeout=30} -- Recurse into any subdirectories that may have other tests. include('dir1/Kyuafile') include('dir2/Kyuafile') File versioning Every Kyuafile file starts with a call to syntax(int version). This call determines the specific schema used by the file so that future backwards- incompatible modifications to the file can be introduced. Any new Kyuafile file should set version to `2'. Test suite definition Every Kyuafile should define the name of the test suite it belongs to by calling the test_suite() function at the very beginning. Individual test programs can override this value in their definition, but the most common style is to list a single test suite name for the whole file. The purpose of the test suite name definition is to tell kyua(1) scoping for the run-time configuration variables that these programs accept. Test program registration A Kyuafile can register test programs by means of a variety of *_test_program() functions, all of which take the name of a test program and a set of optional metadata properties that describe such test program. The test programs to be registered must live in the current directory; in other words, the various *_test_program() calls cannot reference test programs in other directories. The rationale for this is to force all Kyuafile files to be self-contained, and to simplify their internal representation. ATF-based test programs (those that implement the kyua-atf-interface(7) interface) can be registered with the atf_test_program() table constructor. This function takes the name of the test program, an optional test_suite name that overrides the global test suite name and a collection of optional metadata settings for all the test cases in the test program. Any metadata properties defined by the test cases themselves override the metadata values defined here. Plain test programs (those that implement the kyua-plain-interface(7) interface) can be registered with the plain_test_program() table constructor. This function takes the name of the test program an optional test_suite name that overrides the global test suite name and a collection of optional metadata settings for the test program. Please see kyua-tester-list(5) for the list of metadata properties that can be given to test programs. All the properties that can be given to a test case can also be given to a test program. Recursion To reference test programs in another subdirectory, a different Kyuafile must be created in that directory and it must be included into the original Kyuafile by means of the include() function. Note that each file is processed in its own Lua environment: there is no mechanism to pass state from one file to the other. The reason for this is that there is no such thing as a "top-level" Kyuafile in a test suite: the user has to be able to run the test suite from any directory in a given hierarchy, and this execution must not depend on files that live in parent directories. Top-level Kyuafile Every system has a top directory into which test suites get installed. The default is /usr/tests. Within this directory live test suites, each of which is in an independent subdirectory. Each subdirectory can be provided separately by independent third-party packages. Kyua allows running all the installed test suites at once in order to provide comprehensive cross-component reports. In order to do this, there is a special file in the top directory that knows how to inspect the subdirectories in search for other Kyuafiles and include them. The FILES section includes more details on where this file lives. FILES /usr/tests/Kyuafile. Top-level Kyuafile for the current system. /usr/share/examples/kyua-cli/Kyuafile.top. Sample file to serve as a top-level Kyuafile. SEE ALSO kyua(1) FreeBSD 14.1-RELEASE-p8 February 9, 2013 FreeBSD 14.1-RELEASE-p8
