FAQs
How do I use it in an NSF?
Copy the contents of the VoltScriptTesting.bss into a Script Library. Write an agent with Use VoltScriptTesting
.
Where do I find the output?
The output will, by default, be in a "unit-test-reports" directory (defined by the BASE_REPORT_LOC
constant in TestRunner.bss) under the directory of the program running the tests.
If running from a Notes Client, this is the Notes program directory. If running in a scheduled agent, this is the Domino program directory.
How do I change the output directory?
If you wish to change the output directory for every test runner using the script, change the BASE_REPORT_LOC
constant.
If you wish to change the output directory for a single set of tests:
- If using a TestRunner, call
TestRunner.outputTo()
. - If just using a TestSuite independent of a test runner, call
TestSuite.outputTo()
.
WHy is the content outside the NSF?
The output is part of your project reporting. Typically in software development project reporting is not included in the binary deliverable, so it doesn't make sense to include in the NSF being delivered to the customer or end user. HTML is also a more flexible medium for reproducing the kind of output and user experience familiar to developers who have used JUnit.
What are missing assertions?
This means you have called describe()
but a corresponding assertion - or call to addResult()
or addError()
- has not been included. This could be because other code after the describe()
call has generated an error and needs fixing.
I am using a CustomBeforeAfter, but the assertion is not taking into account the value from the beforeEach()
Make sure your code is not running a function that modifies a value being modified in the beforeEach, e.g. assertEqualsDouble(f, CDbl(a))
, where a
is incremented in the beforeEach()
. In the above line, the order of processing would be:
- CDbl(a)
- Call to assertion.
- Run
beforeEach()
, incrementing a. - Run assertion.
If the beforeEach()
is a pure function - i.e. it just instantiates dummy data and does not modify any global variables - you could manually call beforeEach()
before modifying the value that you are passing into the assertion. Alternatively. just compare against the value before the beforeEach()
has run.
What is Recommended Best Practice for Test Suites?
In personal experience, creating a separate function for each TestSuite gives greatest clarity. It also allows aborting a run if a key TestSuite fails. Each TestSuite is usually designed to test a specific process or self-contained aspect of the code or application.
TestSuites for unit tests and integration tests are typically also separated. Unit tests are used to test functions that do not depend on specific environmental aspects - specific users, specific data etc. In other technologies, unit tests will also include mocking.
Integration tests are used to test code that requires specific data to be available, specific user access to be in place, real-world testing of external systems etc.
How Can We Mock Data or Users?
Before/After code can create data specifically for testing - these would then become integration tests.
Java has Mockito framework, because sub-classing is always possible and API calls can be intercepted. That is not an option here. From experience, TestSuite functions are best written in the same file as the functions being tested. The same approach is used for Rust and has the added benefit of documenting how the functions are intended to be used.
If non-LSX custom classes are used as parameters, this may allow sub-classing with a mocked object to test a complete function. More commonly, branching logic needs to be added to the functions to route differently if the callee is a test. If the tests are in the same file as the functions being called, private variables can be used to determine if a test is being run or determine if an error should be thrown.
Testing Means I Have to Write My Functions Differently
Yes, it probably will. Writing code is one thing, writing testable code is a completely different beast, and not specific to any one language. It's not hard to find articles written about this.
