+# XCUITests
+
+After the tests finish execution, the essential thing that we need is the simulator needs to stay alive.
+The problem with `XCUITests` is that after testing finish execution, it quit the simulator.
+
+# Things I've tried:
+
+1. Trying to find a way to preserve the running program after tests finish running
+
+- I can't find any way to preserve the running program.
+
+2. At the end of a test, run shell script to generate `memgraph` before the running program quit
+
+For this idea, I put a breakpoint before the test finish execution. Then we can custom that breakpoint to execute a shell script command.   
+However, when running on CI, we will execute test using script, not from Xcode. So, using breakpoint to execute shell script will not work for CI
+
+=> Only work on Xcode
+
+3. From Xcode13, Apple provide `-enablePerformanceTestsDiagnostics` to generate memgraph after a test finish executing.
+
+```bash
+    xcodebuild test -project MemoryLeaksCheck.xcodeproj \
+        -scheme LeaksCheckerUITests \
+        -destination platform=iOS,name="Tuan iPhone" \
+        -enablePerformanceTestsDiagnostics YES
+```
+
+> Note: In the scheme configuration, open `Options` under `Test`, unselect "Delete if test succeeds" for Attachments.
+
+<img src=../resources/xcuitests.png width=800/>
+
+However, **this only works for real device, not for simulator.**
+
+Based on [Apple docs](https://developer.apple.com/documentation/xcode-release-notes/xcode-13-release-notes)
+
+> xcodebuild has a new option -enablePerformanceTestsDiagnostics YES that collects diagnostics for Performance XCTests. The option collects a ktrace file for non-XCTMemoryMetrics, and a series of memory graphs for XCTMemoryMetrics. xcodebuild attaches diagnostics to the generated xcresult bundle. **Note that memory graph collection isn’t available in simulated devices. (64495534)**
+
+=> Only work on local with real device, doesn't work on CI
+
+# Conclusion
+
+XCUITests is not appropriate for this approach. (for now)

 ## Why I used Maestro?
 
 1. I need a testing tool which doesn't kill the program after the testing finished execution. And Maestro support that. Also Maestro is very easy to integrate & use.  
-2. I've tried to used XCUItest, which is really promissing. Based on this [WWDC video](https://developer.apple.com/videos/play/wwdc2021/10180/) from Apple, XCUITest even *allows us to capture the stacktrace where leaks occur & generate a memgraph*. However, I've tried to follow the video but Xcode didn't generate any memgraph.
