Please add test(s) of the new method.

Yeah, you got me there.

@markbandstra I've added tests of the new method. Something strange is going on with either black or pytest-black in the CI, but tests pass locally.

@jvavrek that is really weird. I triggered the jobs again. This appears to be something in pytest-black which was fixed in: https://github.com/shopkeep/pytest-black/issues/42

@jvavrek can you try pytest-black>=0.3.10

[jccurtis]

@jvavrek also try pytest<7.0.0

[jvavrek]

@jvavrek can you try pytest-black>=0.3.10

ERROR: Could not find a version that satisfies the requirement pytest-black>=0.3.10 (from versions: 0.1.4, 0.1.5, 0.1.6, 0.1.7, 0.1.9, 0.2.0, 0.2.1, 0.3.0, 0.3.1, 0.3.2, 0.3.3, 0.3.4, 0.3.5, 0.3.6, 0.3.7, 0.3.8, 0.3.9, 0.3.10, 0.3.11, 0.3.12)

???

@jvavrek also try pytest<7.0.0

This worked 🚀

Why was the CI installing 7.x when conda and pypi both only have 6.2.5?

Bizarrely, it looks like it was not installing 7.x: https://github.com/lbl-anp/becquerel/runs/4723159061?check_suite_focus=true#step:5:196

Well I'll be scratching my head on that one ... thanks for posting #307 ... I'm sure this will be resolved by the plugin developers eventually
