=== Limitations

The following should be taken into consideration when writing new tests or adjusting existing ones:

==== TLS

`JKS` and `PKCS#12` keystores cannot be used in FIPS mode. If the test depends on being able to use
a keystore, it can be muted when needed ( see `ESTestCase#inFipsJvm` ). Alternatively, one can use
