1 | # This file contains tests for the tclProc.c source file. Tests appear in |

2 | # the same order as the C code that they test. The set of tests is |
---|
3 | # currently incomplete since it includes only new tests, in particular |

4 | # tests for code changed for the addition of Tcl namespaces. Other |

5 | # procedure-related tests appear in other test files such as proc-old.test. |

7 | # Sourcing this file into Tcl runs the tests and generates output for |
---|
8 | # errors. No output means no errors were found. |
