 Testing and analysis
 --------------------
 
+## CI testing
+CI testing is intended to catch major breakages. It does not guarantee
+reproducibility of all bugs.
+
+See [`.github/workflows/ci.yml`](../../.github/workflows/ci.yml) for the set of
+tests that currently run in CI.
+
+## Pre-release testing
+Before making a new release, make sure all of the following are true. See
+*Local testing* below for instructions.
+
+1. All tests running in CI pass.
+
+2. All bugs are reproducible.
+
+3. Code coverage analysis succeeds for all bugs (modulo documented issues).
+
+4. Mutation analysis succeeds for all bugs (modulo documented issues).

 ### Reproducing all bugs (parallel)
-Reproducing all bugs is the most time-consuming test. To speed it up, we use
-GNU parallel (`-j` gives the number of parallel processes):
 ```
-./jobs_verify_bugs.pl | shuf > jobs.txt
-parallel -j20 --progress < jobs.txt
+./jobs_verify_bugs.pl | shuf | parallel -j20 --progress
+```
+Reproducing all bugs (20 jobs in parallel) takes ~3h.
+
+### Code coverage analysis for all bugs (parallel)
+```
+./jobs_coverage.pl | shuf | parallel -j20 --progress
+```
+Running code coverage on all bugs (20 jobs in parallel) takes ~45min.
+
+### Mutation analysis for all bugs (parallel)
+```
+./jobs_mutation.pl | shuf | parallel -j20 --progress
+```
+Running mutation analysis on all bugs (20 jobs in parallel) takes many hours
+(due to a few long-running analyses).

+TODO: We should be able to run this in parallel.
