filter-output(1)

Synopsis

<my-test-program> [<arg> ...] | filter-output

Description

filter-output is a filter, receiving input on STDIN and producing output on STDOUT.

filter-output is usually invoked as part of a test configured using the cet_test() command in order to sanitize the test-output to improve its suitability for comparison with a reference to (e.g.) detect regressions. It may also be used in order to produce such references for later comparison.

Details

The following transformations are performed on filter-output’s input:

  • Recognizable date/time formats -> <date-time>.

  • Variable length separator/filler strings of at least 15 consecutive occurrences of the same symbol (-, =, ., *, ~ or /) -> <separator (<char>)>.

  • Platform identifiers starting with Darwin or Linux -> <platform>.

art

  • Absolute paths to source files ending in _(plugin|module|service|tool).cc are truncated to <path>/.

  • TimeReport values -> <duration>

  • MemReport sections are elided.

Examples

  • $ my-test | filter-output >my-test-ref.out 2>my-test-ref.err

  • cet_test(my-test HANDBUILT TEST_EXEC my-test REF my-test-ref.out my-test-ref.err)
