------------------------------------

             Summary: Use assert(!x) instead of assert(x === false) in 
SecurityManagerSuite
                 Key: SPARK-58709
                 URL: https://issues.apache.org/jira/browse/SPARK-58709
             Project: Spark
          Issue Type: Test
          Components: Spark Core
    Affects Versions: 4.3.0
            Reporter: Uroš Bojanić


SecurityManagerSuite compares boolean results against false, as in 
assert(securityManager.checkUIViewPermissions("user3") === false). All three 
receivers (checkUIViewPermissions, checkModifyPermissions, aclsEnabled) return 
a Scala Boolean, so the comparison adds nothing.

This rewrites the 19 occurrences in the first six tests to the negated form. 
Besides being shorter, the negated form produces a better failure message: 
ScalaTest reconstructs the source expression, so a failure reports the 
offending call and its argument rather than the anonymous "true did not equal 
false".

Test-only, with identical truth values. The remaining occurrences in the later 
tests are left for a follow-up to keep the diff reviewable.
