This package can be tested in the usual Julia way:
# press ] to enter Pkg mode
pkg> test FortranFiles
However, in order to test whether files written by a Fortran program are properly read, this first needs to generate some Fortran output. Therefore the following external dependencies are required to run the tests:
- gfortran (a reasonably recent version, which understands the
- GNU make
The tests perform the following steps:
- Create the Fortran source code, and compile it.
- Create the Julia source code for reading the Fortran data, and for writing it out again.
- Run the Fortran program. This produces the input test data.
- Use the Julia code to read in the test data. Datatype and storage size of the read items are checked against their expected values.
- Use the Julia code to read parts of the test data, i.e. records are skipped or read incompletely.
- Use the Julia code to write the data to an output file.
- Check that the input and output file are identical.
This sequence of steps is performed for each of the tested record types (variable-length records with various types of record markers, and fixed-length records for direct access mode), and each of the supported byte orders, using the appropriate gfortran compiler options to adjust the Fortran output.
