Regular --where test filter with quotes or spaces cannot be passed via @FILE

[k15tfu]

Hi!

It turned out that == operator for test names with quotes or spaces cannot be passed via @FILE, unlike the case when it is passed as command line arguments:

using NUnit.Framework;

namespace nunit_testfilter_csharp
{
    [TestFixture]
    public class Class1
    {
        [TestCase("with spaces")]
        public void Test(string name)
        {
            Assert.AreEqual(name, "with spaces");
        }
    }
}

and run with:

>TYPE ...\NunitWhereArg.txt
"test==/nunit_testfilter_csharp.Class1.Test(\"with spaces\")/"
>tools\nunit3-console.exe ...\bin\Debug\nunit_testfilter_csharp.dll --where @...\NunitWhereArg.txt  --noresult

but it works when passing --where argument as parameters of a command line:

From the documentation for @file...

"Specifies the name (or path) of a FILE containing additional command-line arguments to be interpolated at the point where the @file expression appears. Each line in the file represents a separate command-line argument."

In this case, your aren't passing the full argument but only a part of it...

Instead try either of the following in your file...

--where test==/nunit_testfilter_csharp.Class1.Test("with spaces")/
--test /nunit_testfilter_csharp.Class1.Test("with spaces")/

The second line uses the --test option rather than the --where option.

Note that double quotes need to be escaped with a backslash on the command-line but not in the file. That's a feature. :-)

@CharliePoole Thank you for the quick response!

Instead try either of the following in your file...

The first line doesn't work either:

>TYPE ...\NunitWhereArg.txt
--where test==/nunit_testfilter_csharp.Class1.Test("with spaces")/
>...\tools\nunit3-console.exe ...\bin\Debug\nunit_testfilter_csharp.dll @...\NunitWhereArg.txt --noresult

Each line in the file represents a separate command-line argument

This was my second question, if we are talking about command line parameters:

...\tools\nunit3-console.exe ...\bin\Debug\nunit_testfilter_csharp.dll --where "test==/nunit_testfilter_csharp.Class1.Test(\"with spaces\")/" --noresult

, I'd say --where and test==/nunit_testfilter_csharp.Class1.Test("with spaces")/ are two separate arguments (not one), so in this case I should be able to pass only the latter argument via @FILE but it also doesn't work.

[CharliePoole]

I no longer work on the NUnit project, but it does look as if the particular expression --where test==... may have a bug, which the @nunit/framework-team could address. I do know that --test... has special code to handle double quotes used by NUnit in its test names.

WRT what is meant by an argument, I must admit that the docs could have been more specific. What each line represents is actuall a separate argument as handled internally by NUnit. Depending on how you write it, this may be a single command-line argument or two arguments. For example, compare --where cat=MyCategory and --where:cat=MyCategory.

Additionally, this handling will also vary between operating systems. Consider, for example that most Linux systems handle single quotes specially on the command-line while Windows doesn't. One of the ideas behind both @FILE and --test-list=FILE) was to provide a way of coding arguments that would work across different operating systems. As a result, the syntax differs from what is acceptable in any particular operating system.
