IUNIT IBM i Unit Testing Framework

Welcome to IUNIT. The lightweight extensible unit testing framework for IBM i.
Check prerequisites.

Building in library IUNIT (install and use bash)

git clone https://github.com/i-unit/iunit.git
cd iunit
source build.sh
iunit.restore IUNIT

Test

addlible iunit
runone iunit pass
runall iunit

Using

• Create a test suite library 'mytest'
• Create a CLLE program named 'pass' with this program source.
• addlible iunit
• crtdupobj utemsg iunit *msgf mytst
• addlible mytest
• runall mytest

Create a CLLE program named 'fail' with this program source.
runall mytest

Workings

RUNALL runs all programs in the library that do not start with I_
Fail your test program by sending an escape message to *PRV with sndpgmmsg
Make sure the tests do not hang in QSYSOPR message queue by monitoring all commands. Otherwise they will stall your test
I_SETUP is called before RUNONE and RUNALL run any tests
I_TEARDOWN is called after RUNONE and RUNALL have ran all tests

Best practices

Do not depend one test on the result of another test
A library is set of related tests (a test suite). Create as many libraries as you need and call them sequentially
When using TD/OMS as your change management system. include tests in your compile or transfer

Tips

Copy I_SETUP and I_TEARDOWN source from IUNIT into your test libraries and modify
You can copy IUNIT into your test library so that it is completely self contained
