运行多个测试时，Robolectric会忽略自定义和测试应用程序类

Question

For an Android app, I have Robolectric unit-tests. I run them from Eclipse.

I'm using the Robolectric feature of providing a replacement Application class for Robolectric to use. This class, call it TestApplication , extends my application class, call it MyApplication , which extends the Android Application class.

I've found that, when I run individual test cases, Robolectric uses the substitute Application class as expected. But, if I create a run configuration for all the tests in the project, Robolectric reverts to using the Android Application class. It ignores both TestApplication and MyApplication .

What could be causing this? Thanks in advance!

Answer 1

I encountered a similar problem with robolectric where the suite of tests would fail but a single test would run fine. It turned out there was a timing issues while running the suite. Try adding a wait timer or a sleep and see if it works

Answer 2

It seems the cause of the problem was that Robolectric was not using my project's AndroidManifest.xml when Eclipse ran a "run configuration" for a package or an entire project, as opposed to a single test class.

A fix that works is to use Robolectric's configuration feature to provide the location of the manifest. See here .

Both the @Config and properties file solutions worked for me. I preferred the properties file because it applies to the entire project, whereas the annotation has to be on every test class.

The properties file should be named "org.robolectric.Config.properties" and you should put it on your classpath (I did this by placing the file in the test project's source folder).

Assuming you have a TestMyProject containing Robolectric tests for MyProject , the file should contain the following. (The path below is relative to TestMyProject ).

manifest=../MyProject/AndroidManifest.xml
