This helps fixing https://coveralls.io/builds/65356202/source?filename=src%2Ftrixi_include.jl#L45, but

• https://coveralls.io/builds/65356202/source?filename=src%2Ftrixi_include.jl#L45
• https://coveralls.io/builds/65356202/source?filename=src%2Ftrixi_include.jl#L81

Are still uncovered. Any ideas how to trigger those as well @ranocha ? If not, do we still need that code?

Your test file needs to look like

x = solve(maxiters = 123)

or

x = solve(; maxiters = 1234)

The position of the semicolon is important in the file included via trixi_include - not in the trixi_include command itself!

I'm giving up... it seems like https://coveralls.io/builds/65357802/source?filename=src%2Ftrixi_include.jl#L81 is still not reached 😢.

Maybe some other day (or someone with more time and patience)
