* Revert 1c5291f818

* APIテストの復活

* apiテストの移行

* moduleNameMapper修正

* simpleGetでthrowしないように

status確認しているので要らない

* longer timeout

* ローカルでは問題ないのになんで

* case sensitive

* Run Nest instance within the current process

* Skip some setIntervals

* wait for 5 seconds

* kill them all!!

* logHeapUsage: true

* detectOpenHandlesがじゃましているらしい

* maxWorkers=1?

* restore drive api tests

* workerIdleMemoryLimit: 500MB

* 1024MiB

* Wait what
