伊斯坦布尔没有运行所有茉莉花规格

我有24个测试

jasmine-node spec
........................
Finished in 2.061 seconds
24 tests, 54 assertions, 0 failures, 0 skipped

当我运行伊斯坦布尔时，它似乎只运行了14个测试

istanbul cover jasmine-node spec
..............
=====================================================
Writing coverage object [/Users/jared/git/redacted/redacted/coverage/coverage.json]
etc ..

为什么伊斯坦布尔没有运行我所有的测试？
