| |
| This script scans for the set of unit test applications in the git |
| repository and attempts to execute them. By default, it tries to |
| build each test case on one platform per architecture, using a precedence |
| list defined in an architecture configuration file, and if possible |
| run the tests in any available emulators or simulators on the system. |
| |
| Test cases are detected by the presence of a 'testcase.yaml' or a sample.yaml |
| files in the application's project directory. This file may contain one or more |
| blocks, each identifying a test scenario. The title of the block is a name for |
| the test case, which only needs to be unique for the test cases specified in |
| that testsuite meta-data. The full canonical name for each test case is <path to |
| test case>/<block>. |
| |
| Each test block in the testsuite meta data can define the following key/value |
| pairs: |
| |
| tags: <list of tags> (required) |
| A set of string tags for the testsuite. Usually pertains to |
| functional domains but can be anything. Command line invocations |
| of this script can filter the set of tests to run based on tag. |
| |
| skip: <True|False> (default False) |
| skip testsuite unconditionally. This can be used for broken tests. |
| |
| slow: <True|False> (default False) |
| Don't build or run this test case unless --enable-slow was passed |
| in on the command line. Intended for time-consuming test cases |
| that are only run under certain circumstances, like daily |
| builds. |
| |
| extra_args: <list of extra arguments> |
| Extra cache entries to pass to CMake when building or running the |
| test case. |
| |
| extra_configs: <list of extra configurations> |
| Extra configuration options to be merged with a master prj.conf |
| when building or running the test case. |
| |
| build_only: <True|False> (default False) |
| If true, don't try to run the test even if the selected platform |
| supports it. |
| |
| build_on_all: <True|False> (default False) |
| If true, attempt to build test on all available platforms. |
| |
| depends_on: <list of features> |
| A board or platform can announce what features it supports, this option |
| will enable the test only those platforms that provide this feature. |
| |
| min_ram: <integer> |
| minimum amount of RAM needed for this test to build and run. This is |
| compared with information provided by the board metadata. |
| |
| min_flash: <integer> |
| minimum amount of ROM needed for this test to build and run. This is |
| compared with information provided by the board metadata. |
| |
| modules: <list of modules> |
| Add list of modules needed for this sample to build and run. |
| |
| timeout: <number of seconds> |
| Length of time to run test in emulator before automatically killing it. |
| Default to 60 seconds. |
| |
| arch_allow: <list of arches, such as x86, arm, arc> |
| Set of architectures that this test case should only be run for. |
| |
| arch_exclude: <list of arches, such as x86, arm, arc> |
| Set of architectures that this test case should not run on. |
| |
| platform_allow: <list of platforms> |
| Set of platforms that this test case should only be run for. |
| |
| platform_exclude: <list of platforms> |
| Set of platforms that this test case should not run on. |
| |
| extra_sections: <list of extra binary sections> |
| When computing sizes, twister will report errors if it finds |
| extra, unexpected sections in the Zephyr binary unless they are named |
| here. They will not be included in the size calculation. |
| |
| filter: <expression> |
| Filter whether the testsuite should be run by evaluating an expression |
| against an environment containing the following values: |
| |
| { ARCH : <architecture>, |
| PLATFORM : <platform>, |
| <all CONFIG_* key/value pairs in the test's generated defconfig>, |
| <all DT_* key/value pairs in the test's generated device tree file>, |
| <all CMake key/value pairs in the test's generated CMakeCache.txt file>, |
| *<env>: any environment variable available |
| } |
| |
| The grammar for the expression language is as follows: |
| |
| expression ::= expression "and" expression |
| | expression "or" expression |
| | "not" expression |
| | "(" expression ")" |
| | symbol "==" constant |
| | symbol "!=" constant |
| | symbol "<" number |
| | symbol ">" number |
| | symbol ">=" number |
| | symbol "<=" number |
| | symbol "in" list |
| | symbol ":" string |
| | symbol |
| |
| list ::= "[" list_contents "]" |
| |
| list_contents ::= constant |
| | list_contents "," constant |
| |
| constant ::= number |
| | string |
| |
| |
| For the case where expression ::= symbol, it evaluates to true |
| if the symbol is defined to a non-empty string. |
| |
| Operator precedence, starting from lowest to highest: |
| |
| or (left associative) |
| and (left associative) |
| not (right associative) |
| all comparison operators (non-associative) |
| |
| arch_allow, arch_exclude, platform_allow, platform_exclude |
| are all syntactic sugar for these expressions. For instance |
| |
| arch_exclude = x86 arc |
| |
| Is the same as: |
| |
| filter = not ARCH in ["x86", "arc"] |
| |
| The ':' operator compiles the string argument as a regular expression, |
| and then returns a true value only if the symbol's value in the environment |
| matches. For example, if CONFIG_SOC="stm32f107xc" then |
| |
| filter = CONFIG_SOC : "stm.*" |
| |
| Would match it. |
| |
| The set of test cases that actually run depends on directives in the testsuite |
| files and options passed in on the command line. If there is any confusion, |
| running with -v or examining the test plan report (testplan.json) |
| can help show why particular test cases were skipped. |
| |
| To load arguments from a file, write '+' before the file name, e.g., |
| +file_name. File content must be one or more valid arguments separated by |
| line break instead of white spaces. |
| |
| Most everyday users will run with no arguments. |
