Tests may specify attributes via the
Attr field in testing.Test. Attributes are free-form strings, but this document enumerates well-known attributes with established meanings.
The following attributes may be added to control how tests are run and how their results are interpreted.
Zero or more
group:* attributes can be set to a test to assign it to groups. A group is a collection of tests having similar purposes or characteristics, often (but not necessarily) scheduled together. In automated testing, tests to run are usually selected by groups. If a test belongs to no group, it has no attribute
group:* assigned, that means it will be disabled in automated testing.
Some groups define extra attributes which annotate tests with extra information. They can be set if a test belongs to corresponding groups.
Below is the list of most popular groups and their associated extra attributes:
group:mainline- The default group for functional tests. Tests having this attribute are called mainline tests. A mainline test falls under exactly one of the two categories: informational if it has
informationalattribute; otherwise it is critical. Failures in critical tests justify rejecting or reverting the responsible change, while failures in informational tests are ignored. All informational mainline tests are supposed to be promoted to critical tests.
group:appcompat- A group of ARC app compatibility tests. Below are its sub-attribute:
appcompat_release: A group of ARC app compatibility tests for release testing.
appcompat_smoke: A group of ARC app compatibility tests for smoke testing.
group:crosbolt- Test failures are ignored and the test's performance data are uploaded to crosbolt. When you add this attribute, you also need to add one of
group:wificell- Tests that will run on the wificell fixture. Typically those tests require special hardware (APs, ...) only available in those fixtures. Some WiFi-specific functional tests that do not technically require a wificell are also made part of this group for consistency to simplify the validation of the whole WiFi stack. Its sub-attributes can be classified into two types:
wificell_func: verify basic WiFi functionalities nightly.
wificell_suspend: verify basic WiFi behavior related to suspend/resume nightly.
wificell_cq: Similar to wificell_func, but triggered by CLs that touch specific code paths.
wificell_perf: measure WiFi performance.
wificell_stress: Stress test the WiFi functionalities.
wificell_mtbf: measure Mean Time Between Failures (MTBF).
wificell_unstableis present, the test is yet to be verified as stable; otherwise, the test is stable.
group:wificell_roam- Tests that depends on grover (Googlers only) fixture to run. Subattributes that specify role of the test (required):
wificell_roam_func: verify basic WiFi roaming functionalities.
wificell_roam_perf: measure WiFi roaming performance.
group:labqual- Tests that must pass for devices to go to a low-touch lab.
group:mtp- Tests that will run on the
mtpWithAndroidfixture. Typically those tests require special hardware (Android Phone Connected to DUT) and setup available in the fixture.
See attr.go for the full list of valid attributes.
Several attributes are also added automatically:
bundle:<bundle>- Test's bundle, e.g.
dep:<dependency>- Test software dependency (automatically added).
name:<category.Test>- Test's full name (automatically added).
See the Running Tests document for information about using attributes to select which tests to run.
