I've finished my previous post a bit too soon and was not precise on the ruby-plsql unite test results analysis.
I've decided to dig a bit deeper to validate that ruby-plsql (RSpec) actually support datatype mismatch exceptions where utPLSQL unit testing fails due to oracle implicit datatype conversion.
In my previous posts I did some writngs on UTPLSQL and ruby-plsql.
For long time, while developing Oracle code I was using ruby-plsql to do test driven development for SQL and PL/SQL.
I used to frequently forget how to use some of the functionalities of ruby-plsql, specially after having a longer break and so each time I was referring the Unit Tests supplied for the ruby-plsql library as a reference. They are really nicely documenting how things work and how can they be used. It usually took me few minutes to find the thing I needed.
In my previous posts I have described some differences between utPLSQL and ruby-plsql. This time I want to focus on automating the test execution with each of those frameworks using Jenkins Continuous Integration.
In my previous post I have described the conceptual differences between UTPLSQL and ruby-plsql frameworks for unit testing of Oracle database code.
I have used a message_api package and unit tests for that API using both frameworks as an example.
In this post I will focus on getting the tests to run and the feedback that we can we get from the tests using both frameworks.
Unit Testing is around for quite a while. Since it started to become more and more popular, quite a few tools became available for Oracle database to allow unit testing of the database.
There are the UI based tools like Quest Code Tester (now Dell Code Tester for Oracle), Oracle SQL Developer unit testing. There is DBFit by Goyko Adzic for regression and functional testing of databases (including but not limited to Oracle), there are probably many more of that kind, that I'm not aware of.
There are also pure programming language based frameworks like UTPLSQL and ruby-plsql. There are probably (and hopefully) many more of that sort that I'm not aware of.
Unit tests are meant to be created and maintained by software developers and are to help developers keep their code clean and valid throughout entire project life cycle.
UI based frameworks for unit testing are putting a high abstraction and tight facade between the code and the developer. Those frameworks tend to limit the richness and variety of possible implementations for a test case and therefore are not suited for software developers. The time and cost of development and maintenance for UI-based unit tests is usually way beyond the benefits.
Variety of program units that are possible to develop is infinite and the only limitations to what the unit can do are the programming language boundaries and developers creativity. For this reason itself, it is best to use a programming language of similar or higher flexibility to describe and test the behaviour for a unit.
In this series of article I will focus on two programming language-based unit testing frameworks for Oralce, that I got familiar with and had opportunity to use.
Oracle database does not support ability to obtain number of rows inserted/updated/deleted by a merge operation.
The only value you can obtain is the total number of rows affected by merge operation.
Foreword
Over a month ago I've made a big decision and a shift in my life. I've decided to move to Ireland and start a new career there. Since I moved, I have significant amount of free time, as I no longer waste 3 hours each day on commuting. Also, since my wife still leaves in Poland (for now), I'm all on my own when I finish my work.
Well, maybe that's not 100% true, since now we have Internet with Skype/Hangouts/appear.in and others.
Anyway. I'm not feeling lonely, but rather take advantage of the time that is given to me, to catch up on things I've neglected for some time.
Last week I revealed the numbers standing behind the overhead of calling a Pl/SQL function from within an SQL statement.
I've left two questions open:
- Is it always a performance issue, when you call a PL/SQL function from a SQL statement?
- What can be done to maintain the function encapsulation (have the code DRY) and keep high performance?
