1 # Ocean Interpreter test code
3 Regular testing is, of course, important for developing any software.
4 The Ocean interpreted is no exception. This document allows easy
7 - a collection of test program
8 - the expected output of these programs when run with various arguments
9 - some "Makefile" code to tie it all together.
11 Three different sorts of tests are run. As soon as any fail, the whole
14 1/ Each program is run and the output is compared against the expected
16 2/ Each program is then run under valgrind, and an error is reported
17 if valgrind detects an error, or if it reports and lost or unfreed
19 3/ Each program is parsed and printed, then the result is parsed and printed.
20 The two results must match.
21 4/ Each program is run with a version of `oceani` with test-coverage
22 recording enabled. Once all programs have successfully run and
23 all the coverage data is available, we check that all lines have
24 been tested at least once. A few exceptions are allowed such as
25 lines that call `abort()`. If any non-exceptional lines have not
26 been run, this final test fails.
27 Until the tests suite is (more) completed, we only throw and error
28 if fewer than 75% of the lines have been tested.
30 Each test has a name, which used to identify the section in this file, and optionally some
31 arguments separated from the name by commas. For each test, there is a section named
32 "output:" followed by the name-and-arguments.

703 ## Test code with syntax errors
705 Syntax errors aren't handled well yet - the result is almost always a
706 single message about the first error. So this section will be fairly
707 thin until we add proper parsing recovery in the face of common errors.
709 A special case of syntax errors is token errors, when a token is only
710 accepted because the parser doesn't know quite enough to reject it.
711 There are handled better as they are quite local, so a single test
712 program can trigger most of the possible errors.
714 To handle erronous code, we need a different set of tests, as we need to
715 capture `stderr`. The same test code will be used for type errors too.
716 As error messages contain the line number, and we don't want changes to
717 this file to change the reported numbers, we copy the code into a
718 separate file first, then run from there.

784 ## Tests for type errors
786 Type error don't cause parsing to abort, so we can fit many in the
787 one test program. Some type errors are found during the parse, others
788 during type analysis which doesn't run if parsing failed. So we cannot
789 fit everything in one.
791 These programs were generated by looking for the
792 various places that `type_err()` are called.

1073 ## Test erroneous command line args
1075 To improve coverage, we want to test correct handling of strange command
1076 line arguments. These tests won't use code, so the exiting test types
1077 won't work. So we need to be able to explicitly give the command line,
1078 and the expected output, and have that tested and the coverage assessed.
1079 Rather than having to spell out the whole command name, just give "cmd",
1080 and discard that. Requiring but discarding the command make an empty
1081 command list possible.
