angular8 test environment is configured to generate a packed instruction command packet testing environment

1.angular.json file instructions added at architect buildTest

From location

projects => (your project name) => architect down 
and build instructions serve the same level of instruction

    "buildTest": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/insuranceTest/",

                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.ts"
                }
              ],

                }
              ]
            }
          }
        },    

　　

2. Configure the test environment packed instruction

Open the file package.json

Add in the script

"buildTest": "ng run biService:buildTest --build--optimizer --aot ",

　

3. Use

npm run buildTest

This will execute a packed instruction when the test environment, and the package file will be generated in the test environment dist / insuranceTest path
