 Of course, not all figures produced by matplotlib can be converted without error.
 Notably, [3D plots don't work](https://github.com/matplotlib/matplotlib/issues/7243).

 ### Testing
 
-matplotlib2tikz has automatic unit testing to make sure that the software
-doesn't accidentally get worse over time. In `test/`, a number of
-test cases are specified. Those run through matplotlib2tikz and compare the output with
-a previously stored reference TeX file.
