make a blog post explaining how to run the unittests

Placeholder for all stuff to put in the blog

convenience methods. set according to the environment if PERL5LIB cannot be set in bashrc

export QUATTOR_PERL5LIB=/usr/lib/perl:/home/stdweird/perl5/lib/perl5/

and use

function mvn_run {
    local unsetfn quatenv
    quatenv="PERL5LIB=${QUATTOR_PERL5LIB:-$PERL5LIB} QUATTOR_TEST_LOG_CMD_MISSING=1 QUATTOR_TEST_LOG_CMD=1 QUATTOR_TEST_LOG_DEBUGLEVEL=3"
    # make a subshell with all bashfunctions removed. maven can have issues with then via exporting with env.BASH_FUNC
    unsetfn=""
    for fn in `env |grep BASH_FUNC_ | grep -v grep | sed "s/(.*//; s/BASH_FUNC_//" |tr "\n" ' '`; do
        unsetfn="unset -f $fn; $unsetfn"
    done
    bash -c "$unsetfn $quatenv mvn $1"
}

function mvn_test {
    local extra
    if [ ! -z "$1" ]; then
       extra="-Dunittest=$1.t"
    fi
     mvn_run "clean test -Dprove.args=-v $extra"
}

function mvn_pack {
    mvn_run "clean package -Dprove.args=-v"
}

export -f mvn_run
export -f mvn_test
export -f mvn_pack

There is already documentation here . Feel free to update it.

gather debug logs

yum install -y perl-App-cpanminus.noarch  perl-devel gcc perl-Test-Simple
cpanm install Devel::Trace
perl -t -d:Trace `which ncm-ncd` --co fstab >& fstab_output

if no perl-App-cpanminus, do a yum install -y perl-CPAN, and install the module by

• start cpan
• type install Devel::Trace

[piojo-zz]

Devel::Trace is available on Fedora, isn't it in EL6 or EL7?

[stdweird]

to get value based regexptest for TT, pipe output of verbose mvn_test through

perl -e 'while (<>) { s/^# //; s/([(){}|[\]+\^\*\$\?#])/\\\1/g; s/^/^/; s/$/\$/; s/ {16}/\\s{16}/;s/ {12}/\\s{12}/; s/ {8}/\\s{8}/; s/ {4}/\\s{4}/; print; }'

[stdweird]

if your, ~/.proverc contains --state=new,save, it will always run all tests

For the record, there is a page about unit test in the old wiki that I updated regularly: https://trac.lal.in2p3.fr/Quattor/wiki/Development/Code/TestingComponents. It may be good to start from it and when moved to quattor.org, remove it from the old wiki.

An issue I faced recently is the fact that set_file_contents doesn't make the file visible to get_file without using it with a CAF;;FileWriter. This is pretty unusual (in my case it was because the action done between set_file_content and get_file was silently failing) but this is confusing to see get_file failing... This needs to be documented.

[stdweird]

If rpm packaging fails for no obvious reason (but has Unable to copy files for packaging:), run it with

PERL5LIB=/usr/lib/perl/ mvn package -e -X -Dprove.args=-v  

Then check the output for the created mappings: eg.g

[DEBUG]   (f) mappings = [["/usr/lib/perl/Test" {} from [{"/home/stdweird/.git/quattor/maven-tools/package-build-scripts/target/lib/perl/Test" failIfLocationNotExists:true filter: false}]], ["/usr/share/man" {% 
doc %attr(644,root,root)} from [{"/home/stdweird/.git/quattor/maven-tools/package-build-scripts/target/doc/man" failIfLocationNotExists:true incl:[ChangeLog] filter: false}]]]    

In this example the pom.xml had 2 mappings, and was based on the build-profile, and it seemed to overlay the mappings of te build-profile on the one in use. The ChangeLog include was thus added, and stuff failed.

The components have stuff like <mappings combine.children="append"> when adding new mappings.
Default is merge, you can also specifiy 'overrride' (but it seems it has no impact the way build-profile is made (it's nested, and then this looses all meaning)

[jouvin]

I have the feeling that this issue has been fixed by @stdweird pages on Quattor development... Am I wrong? If yes, please consider adding/updating a documentation page rather than a blog post... See #212.

[ned21]

I guess this is tracking the 7 TODOs listed in http://www.quattor.org/development/unittests.html ?

[jouvin]

Plan is to fix it during April 2018 workshop
