Uwe Schindler updated LUCENE-1769:
----------------------------------
Attachment: LUCENE-1769-2.patch
Improvements, will commit soon:
- separate core/contrib and tag tests completely. Currently the xml files for
test report generation are mixed together, so tag tests overwrite core results.
This was by the way the reason for the defect in clover 1.x - only recorded
test runs were instrumented. Also contrib was missing. The junit report now
generates a separate report for test-tag
- the test results are now also used in clover analysis. This helps when real
JUnit4 tests are used.
> Fix wrong clover analysis because of backwards-tests, upgrade clover to 2.6.3
> or better

> This is a followup for
> [http://www.lucidimagination.com/search/document/6248d6eafbe10ef4/build_failed_in_hudson_lucene_trunk_902]
> The problem with clover running on hudson is, that it does not instrument all
> tests ran. The autodetection of clover 1.x is not able to find out which
> files are the correct tests and only instruments the backwards test. Because
> of this, the current coverage report is only from the backwards tests running
> against the current Lucene JAR.
> You can see this, if you install clover and start the tests. During test-core
> no clover data is added to the db, only when backwards-tests begin, new files
> are created in the clover db folder.
> Clover 2.x supports a new ant task, <testsources> that can be used to specify
> the files, that are the tests. It works here locally with clover 2.4.3 and
> produces a really nice coverage report, also linking with test files work, it
> tells which tests failed and so on.
> I will attach a patch, that changes common-build.xml to the new clover
> version (other initialization resource) and tells clover where to find the
> tests (using the test folder include/exclude properties).
> One problem with the current patch: It does *not* instrument the backwards
> branch, so you see only coverage of the core/contrib tests. Getting the
> coverage also from the backwards tests is not easy possible because of two
> things:
> - the tag test dir is not easy to find out and add to <testsources> element
> (there may be only one of them)
> - the test names in BW branch are identical to the trunk tests. This
> completely corrupts the linkage between tests and code in the coverage report.
> In principle the best would be to generate a second coverage report for the
> backwards branch with a separate clover DB. The attached patch does not
> instrument the bw branch, it only does trunk tests.
