I like that idea. But I wouldn't use Interpolated Strings (C# 6) here, my goal is to keep it compatible with older versions of Visual Studio, too.

Different topic: you wrote travis-ci.

I don't think that your plan will work that easily.
Travis-CI is a Linux environment and uses mono. So the C# part should work, but it won't be able to start the executables, since they are binaries for Windows.

However it might work to retrieve the right executables using apt-get and/or the ready-to-use database setup of travis-ci:

services:
  - mongodb

In both cases the search for the executables needs to be extended.
Something like:
public static MongoDbRunner Start(string dataDirectory = MongoDbDefaults.DataDirectory, string findFolderStartPath = null)

See https://github.com/JohannesHoppe/Mongo2Go/blob/master/src/Mongo2Go/MongoDbRunner.cs#L34 / https://github.com/JohannesHoppe/Mongo2Go/blob/master/src/Mongo2Go/MongoDbRunner.cs#L51

Interesting ok sounds good, I will try those routes. Thank you for your help!

OK, I moved to string.format. Thank you for your recommendation, I have moved to using the mongodb service in travis as suggested and its working like a charm.

Do you mind to send another pull request + readme update about your work to enable Mongo2Go on Travis-CI? :-)

So I actually alternate between if I use Mongo2Go or an alternate temporary DB.

I added a few comments to this commit to explain what I am doing.

Take a look and let me know if you think others would benefit from this approach, the pattern I and colleges have settled on injects the IMongoDatabase. Take a look at https://github.com/G3N7/MonJobs/blob/master/MonJobs.Tests/MongoJobQueryServiceTests.cs for a few examples of how the tests end up looking.

This looks like serious tested and well done-work! 👍 😄

What about a pull request to the Readme.md? You could write that it's technically possible to run this on travis and that people should refer to MonJobs to figure out how it works!

There are other people that are trying the same right now:
see #9

That sounds great, thanks for taking a look. I will send you a pull request sometime next week once my family has left from visiting.
