Naming conventions
Name testing projects as [ProjectUnderTest].Tests
Name testing classes as [ClassNameUnderTest]Test
Name testing functions different styles:
- start with should and write the general idea
void ShouldAddTwoNumbers - start with the name of the function under test and _ and what should it do
void Sum_ShouldAddTwoNumbers - UnitUnderTest_Scenario_ExpectedOutcome
ParsePort_COM1_Returns1
Reporting (& branch coverage)
Manual reports
Open the administration console and write the following (substitute where {guid})
// cd into the test folder
// this one generates a new folder 'TestResults' generating a XML file
dotnet test --collect:"XPlat Code Coverage"
// this creates an improved HTML report
reportgenerator -reports:TestResults\{guid}\coverage.cobertura.xml -targetdir:"coveragereport" -reporttypes:Html
Integrate coverlet with visual studio
Go to Extensions menu and install the plugin Run Coverlet Report.
Then go to Tools > Options > Run Coverlet Report > Change integration type to Collector.
Then run all your tests manually (only the first time) and from then on you can start it through Tools > Run Code Coverage. This command generates a report file.
