No description provided.

This now allows running unit tests - some of them may need to be tweaked or modified.

Solves #34

[pierresouchay]

Not working as seen in https://travis-ci.org/github/haproxytech/haproxy-consul-connect/builds/675704444 because haproxy is not in $PATH

--- PASS: TestChangeFrontend (0.00s)

=== RUN   TestFromHA

    TestFromHA: from_ha_test.go:147: CANNOT Run test because of missing requirement: Failed executing dataplaneapi: exec: already started

--- SKIP: TestFromHA (0.36s)

[pierresouchay]

This is not working as haproxy binary in not in the $PATH

[aiharos]

But the test tries to execute dataplane, and dataplane is already started?

Failed executing dataplaneapi: exec: already started

Haproxy binary is installed with sudo make install into /usr/local/sbin

'haproxy' -> '/usr/local/sbin/haproxy'
'doc/haproxy.1' -> '/usr/local/share/man/man1/haproxy.1'

The path contains /usr/local/sbin

$ export PATH="/home/travis/gopath/bin:/home/travis/.gimme/versions/go1.14.2.linux.amd64/bin:/home/travis/bin:/home/travis/bin:/home/travis/.local/bin:/usr/local/lib/jvm/openjdk11/bin:/opt/pyenv/shims:/home/travis/.phpenv/shims:/home/travis/perl5/perlbrew/bin:/home/travis/.nvm/versions/node/v8.12.0/bin:/home/travis/.rvm/gems/ruby-2.5.3/bin:/home/travis/.rvm/gems/ruby-2.5.3@global/bin:/home/travis/.rvm/rubies/ruby-2.5.3/bin:/home/travis/gopath/bin:/home/travis/.gimme/versions/go1.11.1.linux.amd64/bin:/usr/local/maven-3.6.0/bin:/usr/local/cmake-3.12.4/bin:/usr/local/clang-7.0.0/bin:/usr/local/sbin:

exec: already started there is something else: #37

I did not pay attention, there is no need to call run on command since already run. It works sometimes because this is racy I suspect.

Rebase with #37 and this error should disappear

As demonstrated by the latest commit:

The issue has to be in the tests, either they:
- should not try to start dataplane if it was started already
- stop dataplane as part of each test cleanup

[pierresouchay]

I think #37 will really fix this

[pierresouchay]

@aiharos Can we rebase this PR after merging #37 (racy bug with detection of binaries), and force push on this one to check everything is working as expected?

Of course, already in progress!
