Hi Suhas,

You didn’t turn anything off in your configure line; if you run `ninja` in the build tree that you configured, it should build everything, including tests, and you can run selected tests by running ctest, e.g.

% ctest -R qstring # runs every test that has `qstring` in its name
% ctest -L qtpositioning # runs all the tests in the `qtpositioning` submodule

(however, you use both -developer-build and -prefix, so things might only work after installing, which is somewhat defeating the purpose of -developer-build; I’d remove the -prefix option).

ctest won’t build the test for you, so if you configured with `-DQT_BUILD_TESTS_BY_DEFAULT=OFF` instead of `…=ON`, then you have to build each test explicitly before you can test it, e.g. `ninja tst_qstring`. But then you can also build the `_check` target to build and run the test, e.g.

% ninja tst_qstring_check

To build and run a whole set of tests you’d probably have to write a script that processes the output from `ninja -t targets`. Re-configuring with QT_BUILD_TESTS_BY_DEFAULT=ON is probably a better choice.
