@IeuanWalker Thank you for raising this.
When NSub compares for equality (e.g. Arg.Is<>()
) it relies on the default .NET behavior, meaning that arrays are object and compared by reference not their content.
new object[1].Equals(new object[1]); // false
new object[1] == new object[1]; // false
To make it work you want to provide a lambda to Arg.Is<>()
that compares arrays by their content, e.g. using SequenceEqual
extension or anything else that works for you.
The following test passes:
public interface ITest
{
int Method(object[] args);
}
[Test]
public void Test()
{
var test = Substitute.For<ITest>();
test.Method(Arg.Is<object[]>(x => x.SequenceEqual(new object[1]))).Returns(2);
Assert.AreEqual(2, test.Method([1]));
}
Let us know if you still have questions.
from nsubstitute.
Thanks all the info, for some reason doing it inline like you have didn't work.
But creating the array variable did work -
object[] jobIdSequence = [jobId];
_db.ReportJobs
.FindAsync(Arg.Is<object[]>(x => x.SequenceEqual(jobIdSequence)), Arg.Any<CancellationToken>())
.Returns(new ReportJobTbl
{
Id = jobId,
Job = ReportJobEnum.AddWardToReport,
HangfireId = 1234
});
from nsubstitute.
