java - 当命令行未指定配置文件时，Spring Boot 集成测试无法获取默认配置文件并引发错误

Question

我正在尝试基于 Spring Boot 配置文件运行基于 Selenium 的测试。我已经在我的 pom 中设置了默认配置文件，但测试并没有看到它。

不确定我是否缺少任何配置。

命令(执行测试):

• mvn test -Dspring.profiles.active=google - 工作正常
• mvn test -Dspring.profiles.active=saucelabs - 工作正常
• mvn 测试 - 错误(如下所示)

错误

Answer 1

如果没有指定任何配置文件，spring 会激活默认配置文件。对于默认配置文件，它扫描 application.properties配置值文件。因此，您需要执行以下操作:

• 创建application.properties文件
• 添加base.url=<url for default profile>

之后，它应该可以正常工作。
