运行 在 Android 上的测试失败时不断出现错误
Keep getting an error when a test fails running tests on Android
描述
免责声明：这也发布在 github here as an issue at the wix/Detox 存储库中，因此您可以更好地查看那里的图像。
当 运行 在 Android 模拟器上测试时，如果其中一个模拟器失败，在测试报告的末尾会显示如下错误消息：
detox[8530] ERROR: [cli.js] Error: Command failed: node_modules/.bin/jest --config e2e/config.json '--testNamePattern=^((?!:ios:).)*$' --maxWorkers 1 "e2e"
如果所有测试都通过，则不会出现此消息，如下面link截图所示：

beforeEach(async () => {
await device.reloadReactNative()

it('should be visible the account number', async () => {
const usernameInput = await element(by.id("loginScreen-accountNumber"))
await expect(usernameInput).toBeVisible()
})
// the failing test is below
it("should have welcome screen", async () => {
await expect(element(by.id("WelcomeScreen"))).toBeVisible()
})
})
}
预期行为
我认为预期的行为是测试报告结束而不显示错误。
设备日志
环境：
排毒：16.0.1
React Native：0.61.5
节点：12.16.1
设备：AVD Android Studio Nexus 4 API 28
OS：Ubuntu 18.04.4 LTS
Test-runner（select一个）：Jest（如上图package.json所示）
错误是完全合法的，指出 Detox 按预期工作。
当谈到测试编排和执行时，Detox 实际上只是一个实际测试运行器的包装器——在您的情况下是 Jest（IMO 是更好的选择 :)。 setup guide and explained more elaborately in the more specific guide for setting up Jest:
中提到了这一事实
As already mentioned in the Getting Started guide, Detox itself does not effectively run tests logic, but rather delegates that responsibility onto a test runner.
Jest is the recommended runner for projects with test suites that have become large enough so as to require parallel execution.
反过来，这也会影响 Detox CLI 的功能 - 即使用适当的参数简单地执行测试运行程序。所以，总而言之，当所有测试都通过时，Jest 成功结束，并且无声。当某事失败时，Jest 会记录一个错误，给出导致错误的线索，告诉每个人它失败了，并且 returns 一个非 0 值。这与您所描述的完全一致。

e2e文件夹如下：
1)
init.js
const detox = require("detox")
const config = require("../package.json").detox
const adapter = require("detox/runners/jest/adapter")
jest.setTimeout(120000)
jasmine.getEnv().addReporter(adapter)
beforeAll(async () => {
await detox.init(config)
})
beforeEach(async () => {
await adapter.beforeEach()
})
afterAll(async () => {
await adapter.afterAll()
await detox.cleanup()
})
- 2)
config.json
{
"setupFilesAfterEnv": ["./init.js"],
"testEnvironment": "node"
}
- 3)
firstTest.spec.js测试失败的测试套件
{
describe("Example", () => {
beforeEach(async () => {
await device.reloadReactNative()
})
it('should be visible the account number', async () => {
const usernameInput = await element(by.id("loginScreen-accountNumber"))
await expect(usernameInput).toBeVisible()
})
// the failing test is below
it("should have welcome screen", async () => {
await expect(element(by.id("WelcomeScreen"))).toBeVisible()
})
})
}
预期行为
我认为预期的行为是测试报告结束而不显示错误。
设备日志
环境：
排毒：16.0.1
React Native：0.61.5
节点：12.16.1
设备：AVD Android Studio Nexus 4 API 28
OS：Ubuntu 18.04.4 LTS
Test-runner（select一个）：Jest（如上图
package.json所示）
错误是完全合法的，指出 Detox 按预期工作。
当谈到测试编排和执行时，Detox 实际上只是一个实际测试运行器的包装器——在您的情况下是 Jest（IMO 是更好的选择 :)。 setup guide and explained more elaborately in the more specific guide for setting up Jest:
As already mentioned in the Getting Started guide, Detox itself does not effectively run tests logic, but rather delegates that responsibility onto a test runner.
Jest is the recommended runner for projects with test suites that have become large enough so as to require parallel execution.
反过来，这也会影响 Detox CLI 的功能 - 即使用适当的参数简单地执行测试运行程序。所以，总而言之，当所有测试都通过时，Jest 成功结束，并且无声。当某事失败时，Jest 会记录一个错误，给出导致错误的线索，告诉每个人它失败了，并且 returns 一个非 0 值。这与您所描述的完全一致。
