OK, so you now have two projects in Eclipse, MyProject and
MyProjectTest.
MyProject's files are in <someworkspace>/MyProject. From now on, I'll
just abbreviate this /MyProject.
MyProjectTest's *files* are in /MyProject/tests. For this reason, you
have two projects, but one of them has its files completely within the
other one.
*Just as a note*, you will see that the Project Explorer node for
MyProject has sub-nodes for the MyProject files and *also* for the
MyProjectTest files.
You should run the tests from MyProjectTest, by selecting the
MyProjectTest node in Project Explorer, and then right-clicking and
selecting Run As > Android JUnit Test.
To say this another way, on your disk you have the following directory
structure
/MyProject/
src/
gen/
res/
tests/
src/
gen/
res/
*In Eclipse*, the project MyProject is associated with the directory /
MyProject/. The project MyProjectTest is associated with the
directory /MyProject/tests.
The point of having tests/ inside MyProject is to keep the tests near
the source code they're testing. That way, if you have to move, share,
backup, restore, or whatever your source files, you're much less
likely to forget the tests.
You still need to have two *projects* at the same level in Eclipse
because you use different tools to run them. You can't run a test
project as an Android application, and you can't run an Android
application as a test project. I think that you may want to click some
button to run one or more tests that you've pre-associated with an
application project. That is, you'd like a single button associated
with your application that runs the tests for the application. It's
certainly possible to do this in Ant, by setting up the proper target.
It's an interesting idea.
