`arguments` - Arguments passed to the run executable.
|
|
`executable` - Name of the executable to invoke.
|
|
`match` - Function to use for compating actual and
|
|
expected file contents.
|
|
`boost_build_path` - Boost build path to be passed to the run
|
|
executable.
|
|
`translate_suffixes` - Whether to update suffixes on the the file
|
|
names passed from the test script so they
|
|
match those actually created by the current
|
|
toolset. For example, static library files
|
|
are specified by using the .lib suffix but
|
|
when the "gcc" toolset is used it actually
|
|
creates them using the .a suffix.
|
|
`pass_toolset` - Whether the test system should pass the
|
|
specified toolset to the run executable.
|
|
`use_test_config` - Whether the test system should tell the run
|
|
executable to read in the test_config.jam
|
|
configuration file.
|
|
`ignore_toolset_requirements` - Whether the test system should tell the run
|
|
executable to ignore toolset requirements.
|
|
`workdir` - Absolute directory where the test will be

|
run from.
|

`pass_d0` - If set, when tests are not explicitly run

in verbose mode, they are run as silent
|

(-d0 & --quiet Boost Jam options).

Optional arguments inherited from the base class:

`description` - Test description string displayed in case

`subdir` - List of subdirectories to automatically
|
|
create under the working directory. Each
|
|
subdirectory needs to be specified
|
|
separately, parent coming before its child.
|
|
`verbose` - Flag that may be used to enable more
|

verbose test system output. Note that it

does not also enable more verbose build

system output like the --verbose command

line option does.
