* [python] [tests] Support overriding library path via environmentMichal Gorny2018-10-111-0/+5
| | | | | | | | | | | | | | | | | Support a new CLANG_LIBRARY_PATH environment variable for the Python binding tests. This variable can be used to force the bindings to load libclang.* from a specific directory. I plan to use this when integrating Python binding tests with the CMake build system. Currently, those tests load libclang.so from default search paths, so I would have to rely on platform-specific mechanics such as LD_LIBRARY_PATH. Instead of copying the whole logic necessary to handle platform differences into yet another place, it's easier to just add a dedicated variable for this purpose.

* [python] [tests] Fix test_linkage for unique external linkageMichal Gorny2017-11-111-1/+2
| | | | | | | | | | | | Starting with r314037, anonymous namespaces no longer give unique-external linkage to variables. However, this linkage can still be achieved by using a type which is not exterally visible, e.g. through being declared in an anonymous namespace but used outside it. Fix the test to take advantage of that. Differential Revision: https://reviews.llvm.org/D39810 llvm-svn: 317986
* [python] [tests] Rewrite to use standard unittest moduleMichal Gorny2017-11-101-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the tests from using plain 'assert' mixed with some nosetests methods to the standard unittest module layout. Improve the code to use the most canonical assertion methods whenever possible. This has a few major advantages: - the code uses standard methods now, resulting in a reduced number of WTFs whenever someone with basic Python knowledge gets to read it, - completely unnecessary dependency on nosetests is removed since the standard library supplies all that is necessary for the tests to run, - the tests can be run via any test runner, including the one built-in in Python, - the failure output for most of the tests is improved from 'assertion x == y failed' to actually telling the values.
