## Motivation: There is no way to run code statically like in Obj-C using `+ [NSObject initialize]`, so this ensures (through a new `SwiftLint` rule) that all test classes inherit this common test class instead of `XCTestCase` directly. A future PR will make use of this new `CIRCLECI_TESTS_GENERATE_SNAPSHOTS` environment variable to allow regenerating snapshots in CI. I've also moved the duplicated `CurrentTestCaseTracker` usages to a single point.
