在IntelliJ中但不在命令行上运行JUnit 5测试时出错

Question

The following error is reported when I attempt to run a simple JUnit 5 test in IntelliJ:

I am using Intellij v2017.1.2.

When I run the test from the command line there are no errors reported.

I've seen various posts reporting similar problems for different versions of IntelliJ but the suggested solutions don't help.

Answer 1

The JUnit User Guide suggests to use 2017.3 or newer.

IntelliJ IDEA releases prior to IDEA 2017.3 bundle specific versions of JUnit 5. Thus, if you want to use a newer version of JUnit Jupiter, execution of tests within the IDE might fail due to version conflicts.
