The order of building modules is determined by the
go system itself. If you want to build an individual module (assuming all dependent modules have previously been build) try something like:
In this case,
test is a target in that directory's
As you see ‘build targets’ scroll past in the log, you may want to run them individually.
go can run them individually, by target name as long as
:run is appended (see above).
jar on the PATH
Although the build system is based on rake it‘s strongly advised to rely on the version of JRuby in
third_party/ that is invoked by
go. The only developer type who would want to deviate from this is the “build maintainer” who’s experimenting with a JRuby upgrade.
Note that all Selenium Java artefacts are built with Java 6 (mandatory). Those will work with any Java >= 6.
If you plan to compile the IE driver you also need:
The build will work on any platform, but the tests for IE will be skipped silently, if you are not building on Windows.
For an express build of the binaries we release run the following from the directory containing the
./go clean release
All build output is placed under the
build directory. The output can be found under
build/dist. If an error occurs while running this task complaining about a missing Albacore gem, the chances are you're using
rvm. If this is the case, switch to the system ruby:
Of course, building the entire project can take too long. If you just want to build a single driver, then you can run one of these targets:
./go chrome ./go firefox ./go htmlunit ./go ie ./go opera
As the build progresses, you‘ll see it report where the build outputs are being placed. Of course, just building isn’t enough. We should really be able to run the tests too. Try:
./go test_chrome ./go test_firefox ./go test_htmlunit ./go test_ie
Note that the
test_chrome target requires that you have the separate Chrome Driver binary available on your
If you are interested in a single language binding, try one of:
To run all the tests just run:
This will detect your OS and run all the tests that are known to be stable for every browser that's appropriate to use for all language bindings. This can take a healthy amount of time to run.
To run the minimal logical Selenium build:
To get a list of tasks you could build, do:
As a side note, none of the developers run tests using Cygwin. It is very unlikely that the build will work as expected if you try and use it.
The tests in this directory are normal HTML files with names ending with
Ignore the Maven POM file present in the same directory. It is only used for releasing to jars to Maven Repository (public or local), and is not considered the main build mechanism.
Here is thepublic Selenium Maven repository.
./go only makes a top-level
build directory. Outputs are placed under that relative to the target name. Which is probably best described with an example. For the target:
The output is found under:
If you watch the build, each step should print where its output is going. Java test outputs appear in one of two places: either under
build/test_logs for JUnit or in
build/build_log.xml for TestNG tests. If you'd like the build to be chattier, just append
log=true to the build command line.
More general, but basic, help for ‘go’ ...
go is just a wrapper around Rake, so you can use the standard commands such as
rake -T to get more information about available targets.
If it is not clear already, Selenium is not built with Maven, it is built with Crazy-Fun though that is invoked with
go as outlined above so you do not really have to learn too much about that.
That said, it is possible to relatively quickly build selenium pieces for Maven to use. You are only really going to want to do this when you are testing the cutting-edge of Selenium development (which we welcome) against your application. Here is the quickest way to build and deploy into you local maven repository (
~/.m2/repository), while skipping Selenium's own tests.
./go release cd maven mvn clean install
This sequence will push some seven or so jars into you local Maven repository with something like ‘selenium-server-2.0-SNAPSHOT.jar’ as the name.
