We have been building geckodriver on TaskCluster for a year and a half, but it has so far not been enabled by default in local developer builds.
With a change that landed yesterday, geckodriver is included in the default build configuration also for local developer builds. It will not be built if --disable-tests is used. You can also explicitly disable building it with --disable-geckodriver. geckodriver is our implementation of WebDriver, and in m-c, used to back a subset of WPT tests. It is also a product in its own right, in that it is used by several major websites that we care about to help web compatibility. As we roll out support for more platforms we expect to expand its in-tree use. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
