This patch replaces LEVEL variable by REGTESTS_TYPES variable which is more
mnemonic and human readable. It is uses as a filter to run the reg tests scripts
where a commented #REGTEST_TYPE may be defined to designate their types.
Running the following command:
$ REGTESTS_TYPES=slow,default
will start all the reg tests where REGTEST_TYPE is defines as 'slow' or 'default'.
Note that 'default' is also the default value of REGTEST_TYPE when not specified
dedicated to run all the current h*.vtc files. When REGTESTS_TYPES is not specified
there is no filter at all. All the tests are run.
This patches also defines REGTEST_TYPE with 'slow' value for all the s*.vtc files,
'bug' value for al the b*.vtc files, 'broken' value for all the k*.vtc files.
Add LEVEL #4 regression testing files which is dedicated to
VTC files in relation with bugs they help to reproduce.
At the date of this commit, all VTC files are LEVEL 4 VTC files.
Since bbc34e2 varnish commit (for varnishtest), a new "cli"
macro is automatically created for each VTC script to dialog with
the CLI. Consequently, as this macro is unknown from higher level
code for varnishtest, it makes the scripts fail if we
we do not ask varnishtest to disregard the unknown macros.
To prevent this, from now on, for each VTC file for haproxy we MUST add
"feature ignore_unknown_macro" line to do so. This is mandatory
