Demo Code

• This talk is partly demo-based
• The demo code is at:
  • github.com/claremacrae/approvals_live_demo
  • As I give this talk, I tag the versions presented, as the demos and ApprovalTests.cpp library will evolve over time:
    • Tag: 2020-09-cppcon: CppCon 2020, 16 September 2020

Appendix

Qt Test Info

• Example: QGIS Unit Testing and QGIS's test code
• Generally useful pages
  • Increase your QTest productivity - another auto-registering mechanism, how to create fixtures, and colour-coding test output

Qt Test executables

• Qt Tests only supports one test QObject per executable, generating large numbers of exes
• Various people have tried to work around this - the following links may be useful
  • Unofficial Qt Creator Blog on "Running Multiple Unit Tests" in one Qt Test program
  • Jaded Biologist on "Using QtTest Effectively"
