Builed failed: Execution failed for task ':url_launcher_android:testDebugUnitTest'. when I installed url_launcher: ^6.1.7

Question

Refer to my previous question ERROR:flutter/runtime/dart_vm_initializer.cc(41) on url_launcher , I'm doing./gradlew build to my android directory on project, but it show the error that

 Execution failed for task ':url_launcher_android:testDebugUnitTest'.
        > There were failing tests. See the report at: file:///C:/projectflutter/hospital-list/build/url_launcher_android/reports/tests/testDebugUnitTest/index.html

I don't know what is happened on here, and it seems impossible for url_launcher to having bug inside, so anyone knows where the problem is? i really want to finish my project and it's only failed on url_launcher
