CodeBuild不报告失败的测试

我正在使用CodeBuild来构建我的NPM项目。我的buildspec中有一个特定的报告组,我正在使用Jest和 npm test 命令

当所有测试都通过时,它们会成功地报告给CodeBuild报告组。但是,如果其中一个测试失败,我会得到错误:

[Container] 2020/08/24 01:41:18 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: npm test -- --silent. Reason: exit status 1`

构建会停止(一般来说这很好),但没有报告失败的测试,所以测试通过率保持在100%,这意味着我看不到测试趋势或其他细节。

我的buildspec的相关部分。yml:

version: 0.2
phases:
  install:
    commands:  
      - npm install
  pre_build:
    commands:
      - npm test -- --silent    
reports:
  jest_reports:
    files:
      - 'test-results.xml'
    file-format: JunitXml
    base-directory: "reports/results"

Jest配置在我的包中。json:

"jest": {
    "reporters": [
        "default",
        [
            "jest-junit",
            {
                "outputDirectory": "reports/results",
                "outputName": "test-results.xml"
            }
        ]
    ]
}

代码构建日志的最后一部分:

Test Suites: 1 failed, 8 passed, 9 total
Tests:       2 failed, 57 passed, 59 total
Snapshots:   0 total
Time:        3.034s
npm ERR! Test failed.  See above for more details.

[Container] 2020/08/24 01:41:18 Command did not exit successfully npm test -- --silent exit status 1
[Container] 2020/08/24 01:41:18 Phase complete: PRE_BUILD State: FAILED
[Container] 2020/08/24 01:41:18 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: npm test -- --silent. Reason: exit status 1

我如何设置CodeBuild来报告失败的测试,但如果测试失败,如何仍然阻止它继续构建?
