fde23c5d0a feat(nix/runTestsuite): add assertDoesNotThrow
assertDoesNotThrow is like assertThrows, but fails if the expression
throws. In that case the new unexpected-throw branch of AssertErrorContext
is returned.

00f79da358 refactor(nix/runTestsuite): implement in terms of generic assertBool
Refactor assertEq and assertThrows to be implemented in terms of a more
generic assertBool to reduce code duplication and ease adding new assert
types.

To preserve meaningful error messages AssertResult is changed slightly:
nope-eq and nope-throw have been replaced by a single nope branch which
contains an AssertErrorContext which contains error information. To
implement an assert assertBoolContext (which is not exposed) can be
used: It takes an AssertErrorContext which is returned in case of an
error and a boolean determining whether the assert was successful.

The currently possible AssertErrorContext are:

* should-throw: error result of assertThrows, formerly nope-throw
* not-equal: error result of assertEq, formerly nope-eq

f4a4da134b feat(nix/runTestsuite): add assertThrows
Uses `builtins.tryEval` to check that the expression throws when
`deepSeq`-ed.

7f091079ce fix(nix/runTestsuite): wrap runTestsuite into derivation
Previously we would throw or return `{}`, which doesn’t integrate
nicely into our CI; thus, let’s wrap it into a derivation which either
fails the build or doesn’t.

c8e888c1d2 feat(nix/runTestsuite): add runTestsuite
This is a very simple test suite for nix expressions.
It should help us set up a good suite of unit tests for our nix-based
stuff.

Since we allow import from derivation, these tests can also depend on
derivations and e.g. use `builtins.readFile` to check outputs.

This is a first PoC to get us going, we can always replace it by
something different in the future if we don’t like it.
