| # Runtests |
| |
| Runtests is a command line tool that runs tests. |
| |
| The most complete documentation of its capabilities and interface is the usage |
| string it prints. |
| |
| It may be useful to developers working with the bringup |
| [product configuration](/products/README.md#bringup), since `fx test` does not |
| support running tests in that configuration. In this configuration, it can be |
| invoked from the serial console as `runtests`. To see a list of all the tests |
| are on the device's Boot FS, run `runtests --all -d`. |
| |
| It is used in continuous integration infrastructure in the following ways: |
| |
| * In coverage profile builders it is used since it knows how to set up |
| collection of coverage profiles. See |
| [fuchsia-run-test.cc](/zircon/system/ulib/runtests-utils/fuchsia-run-test.cc). |
| * In bringup builders it is used to run one test at a time. It's useful (vs |
| just invoking the tests directly) because it enforces timeouts and |
| translates exit codes into predictable strings that are written to the |
| serial console, which are then interpreted by testrunner. |
