Testing

Testing Fortran programs is important to ensure that the software functions as intended. The following sections describe how to test Fortran programs at various levels.

Unit Testing for Code Modules

Need to evaluate unit testing options for Fortran code.

Functional Testing for Operational Features

Need to evaluate functional testing options for Fortran programs.

Systems Testing for Integrated Software

Systems testing refers to testing a Fortran program with other programs that comprise a system. For example, testing may include:

• testing hand-off between programs via command-line, files, or other methods
• running multiple processes at the same time
• interactions with databases or web components

Additional information will be included here in the future.

Performance Testing

At a minimum, performance testing involves timing program execution. More in-depth performance testing may involve evaluating time spent loading software, reading data, writing output, performing computations, etc.

Need to describe whether Eclipse/Photran has performance evaluation features.

See also logging, which is helpful for writing messages when evaluating performance.
