Subject Re: is Travis build for master broken
Date Tue, 04 Oct 2016 23:48:33 GMT
Hey Julian,

Thanks for the tip! Wercker clones with a depth of 50 by default. I have 
now added a few more commands to convert the shallow clone to a full clone.

I am now able to run the tests and get them passing. Wercker is also 
quite stable, I ran the tests a few times and they all pass each time.

Compare to travis, wercker is also much faster, tests take about 9 
minutes to run compared to the 25ish minutes with travis.

Would you be interested in moving the CI over to wercker? You can check 
out my branch here: 
(.travis.yml is replaced with wercker.yml).
