Some of the unit tests in `convertCompilerOptionsFromJson.ts` have long lines that are difficult to edit as the message text increases in size: https://github.com/microsoft/TypeScript/blob/2a01f923caf06b011dbd0d6b0cb1ccc0d5a0f092/src/testRunner/unittests/config/convertCompilerOptionsFromJson.ts#L298 We should consider changing these tests to use baselines/snapshots instead of inline code.
