Invalid characters in test name breaks test runner

• versions: NUnit 3.0 and NUnit Adapter 3.10.0.21

• Visual Studio Professional version 15.8.5

• .NET framework is 4.6.1

• When a test with a custom name has invalid characters in that name (in this case, ‘&’), the nunit adapter throws an error and the tests are removed from the window

• Only appears to happen when you select a group of tests

• Doesn’t appear to happen on other machines

• repro: https://github.com/laura-campbell/nunit3bug

public class Class1
{
        [TestCaseSource("testcases")]
        public void foo()
        {
        }
        public static IEnumerable<TestCaseData> testcases { get; } = new[] { new TestCaseData().SetName("&") };
}

test is visible after building the solution

chose to run selected tests on a group of tests

test is not run and disappears from the window

Error message:

[9/27/2018 11:47:55 AM Error] An exception occurred while invoking executor 'executor://nunit3testexecutor/': Incorrect format for TestCaseFilter Error: Missing operand. Specify the correct format and try again. Note that the incorrect format can lead to no test getting executed.

I have the same problem - just me and non of my colleges. In my case the error caused by character ‘=’. Replacing ‘=’ characted with ‘equals to’ resolved the problem.

Excellent, thanks. That will increase the priority then, especially since & is used in URI query params as you mentioned.
