Test Suite

Liblas includes a test suite written in C++ that can be fairly easily run to ensure that the library is working properly.

make test

The test suite can be run in the liblas main directory with:

make test

If the liblas_test binary does not exist it may be necessary to do:

make liblas_test test

This should produce a brief report indicating the number of tests that failed, if any. A detailed report will be generated in liblas/Testing/Temporary/LastTest.log. Failure reports may look something like:

---> group: liblas::SpatialReference, test: test<6>
     problem: assertion failed
     failed assertion: `VLR count: expected `3` actual `4``

Tests failures diagnosis may require inspecting the test code in the liblas/test/unit directory. In the above case searching for “test<6>” in the file liblas/test/unit/lasspatialreference_test.cpp would be appropriate.

The tests can also be run directly in the liblas/test/unit directory by running the liblas/bin/liblas_test executable. In this case the report is written to stderr. Be careful to write it in the right directory or some tests will fail for reasons that are not clear.

Continuous Integration - TravisCI

The libLAS project uses Travis to perform automated builds and continuous integration.

Building libLAS and running unit tests using CMake on Unix

Users are encourage to run libLAS unit tests and submit test results to dedicated CDash - utility dashboard hosted by the http://cdash.org website:

The CDash_ is another tool libLAS uses to perform continuous integration during development process.

  • Configure libLAS core library with unit tests enabled

Ammending and Extending the Test Suite

The tests for the test suite are implemented as a set of C++ files in the liblas/test/unit directory. New tests for existing classes can be added based on the existing examples. New files can be introduced for additional classes or categories of testing, but the source filename(s) will also need to be added in liblas/test/unit/CMakeLists.txt.
