The builders can also be used in your production code — they aren’t just test helpers. In this example, we extracted the code that creates a new test context (empty data).
[Fact]
void RunBeeReport()
{
var sightingDate = Arbitrary.DateTime();
using InitialData.Empty();
IncludeData.BeeSighting(sightingDate)
.InCounty(Arbitrary.ForeignCounty)
.Build();
var testSubject = Helpers.CreateReportPage();
testSubject.DoRunReport(ReportTypes.Honeybee,
Arbitrary.DateBefore(sightingDate),
Arbitrary.DateAfter(sightingDate),
Arbitrary.ForeignCounty);
testSubject.CurrentReport().Should()
.BeValidBeeReport()
.WithData(sighting);
}
