“#PL/SQL: Therefore, whoever binds forever: automate your tests” – I’m a speaker at #DOAG2017

 

Today my presentation is confirmed: “Therefore, whoever binds forever: automate your tests”. Maybe the German pun will be the better understood: “PL/SQL: Drum test-automatisiere, wer sich sich ewig bindet!”

I will speak over my experiences with following

  • several PL/SQL testing tools like at least
  • I will give you a demo of this tools and compare their capabilities for
    • architecture
    • branching
    • continuous integration
    • code coverage

If you speak german and you are interested in some of this, you should come and attend DOAG 20157.

#DEVCAMP17 wrap up

 

Yesterday I attend the annual barcamp DEVCAMP of the DOAG development community. There are mostly developers with SQL, PL/SQL, Forms & Reports, ADF, JET background and some Java, Javascript and APEX developers too. And not to forget: 1 dba and some managers. Here are my summary.

I arrived on evening before just in time for the life cooking event and later at the bar to meet lot of the people I already know and some new too.

The morning begins with a short introduction to the format of a barcamp.

As warm up Jens Schauder starts with an talk about clean code. He begins to compare what the lack of hygiene for Middle Ages mean and the statement that we are in the IT Middle ages. In extreme cases not tested and not understandable software can kills people! So the task for every day is “write an test” and refactor the code to clean code.

Then the barcamp planning starts. In short time three slots are filled up and the really barcamp starts.

Influenced by the starting talk next there was a session related to clean code and how to implement the related processes. You should teach a little bit of the theory behind it. It is essential to decide all rules with the whole team and review the continuous use of it. If the rules are not followed, then first you should ask why this happens and listen for the reasons. Jens Schauder recommends here these books. Maybe you have to adjust the rules to convince all developers. But in extreme cases of deny any of the decided rules you should escalate and delegate this to the responsible manager.

Next session was about how to test heterogeneous applications, especially SQL, PL/SQL and Forms but others too. I mentioned here two possible strategies, which both has it’s tradeoffs:

I noticed here that testing is mainly seen as to check the contract between developer and customer, sometimes useful for regression test but seldom as required for changing or refactoring the code. The participants seems to be overwhelmed by the amount of tools and effort to do automatic testing. Yes – there is a lot to do in advance, which pays off later.

In the next break I get a shortcut for actual requirement for forms change to implement some kind of SSO without additional servers. I get some nice hints and have now to check, if one of this is successful. This are the advantages of networking here.

The we discussed about Alternatives to Oracle Reports. Seems that it depends on your requirements, which tool to choose. Please do an value analysis here. So if you need pixel exact layout or want not pay much money Oracle Business Intelligence Publisher will not your friend. If you search for an active community maybe you should not choose Eclipse BIRT or at least use the commercial version from Actuate. But both of these and Jasper Reports are used from present participants. Further alternatives seem to be SAP Chrystal Reports and Pentaho. And don’t forget to test exotic features like widows and orphans!

After a coffee break we discussed the future of Oracle ADF. The punchline here was: ADF is not dead, but JDeveloper is very buggy. None of the participants does really miss any bit feature, but most struggles with the IDE. It seems, that the problems are bigger, when you work on windows. Maybe some of the product managers should be forced to worked again with windows to see our problems. I have articulated there 2 problems with the ADF community. I we try to raise the acceptance we should not try to extend the focus of the activities to alternative technologies as MAF or JET. Second we should not self call ADF into question on every conference, we should leave this part to the fans of other technologies.

The last session again turns around automatic testing of PL/SQL, some repeating to the described session above.

In closing session most of the participants said, that they want to come back next year. Maybe it is better to put some fixed sessions or workshops, as this is easier to describe to the bosses as “I will go this event, but it is not clear, what will happens there.”

Conclusion

I have learned not so much new things this year, but I attend these time more the known to me technologies. But I get the confirmation, that most of the things we do or plan do to are on the right track.

Unfortunately I observed some people in the sessions, which comes only to search for finding confirmations to reject for itself, what at least the initiator of the topic want to do.
