Question

I have some chart rendering tasks that I want to cover with tests. I used svg renderer in my tests. At first run I generate some files. At next runs I want to compare output with first run results. If they are different tests should fail. It was just fine. The issue is that such rendering is platform depended. So that I cannot run same tests on Linux and Windows. I don’t like it at all. How can I write cross platform tests for stuff that used JFreeChart?

Ok. I solve this issue. If someone have same issue keep in mind next hints

1. JFreeChart use platform specific fonts by default. So you should distribute your ttf font and set it explicitly for each label. You can load font by Font.createFont.
2. Use specific locale. You can set default locale for your test by next code Locale.setDefault(Locale.US);
