Unit Testing with Mock Objects (Week 6)

This article is posted by IBM and explains how the Mock Object can be used. In this article we will find some of the benefits of using Mock Objects for writing Unit tests for objects that act as mediators. Unit testing has become widely accepted for software development. When you write an object you must also provide an automated test class containing methods that put the object through its paces, calling its various public methods with various parameters and making sure that the values returned are appropriate.When we’re dealing with simple data or service objects, writing unit tests is straightforward. However, many objects rely on other objects or layers of infrastructure. When it comes to testing these objects, it is often expensive, impractical, or inefficient to instantiate these collaborators. For example, to unit test an object that uses a database, it may be burdensome to install, configure, and seed a local copy of the database, run your tests, then tear the local database down again.A mock object conforms to the interface of the real object, but has just enough code to fool the tested object and track its behavior. For example, a database connection for a particular unit test might record the query while always returning the same hardwired result. As long as the class being tested behaves as expected, it won’t notice the difference, and the unit test can check that the proper query was emitted.

Here are some of the common coding style for testing with mock objects:

  • Create instances of mock objects
  • Set state and expectations in the mock objects
  • Invoke domain code with mock objects as parameters
  • Verify consistency in the mock objects

How can SQL help your testing abilities? (Week 5)

The reports that SQL can generate transforms raw information into useful data also can be used as a tool that can help to refine your testing abilities. The methods that SQL provide can help perfect the skills of programmers. The methods help to get correct results  when we testing back-end applications.SQL is a parent-child relationship schema that allows information to be accessible and allows to minimize discrepancies across data which create reliable output tables.The tables with columns and rows that build up the records of employment can help the End user have a interactive graphical Interface. The interactive graphical interface it can help the users to make changes. SQL is used in a variety of testing tools; the tools that are used mostly to select information that is relevant and can provide insight into the business practices. Some of the automation tools that is used to create a quality product are QTP and Selenium. QTP provides functional test automation for software applications and environments and Selenium is a free (open source) automated testing suite, Selenium is used to test web applications. Both tools use different languages QTP  run on Java and Selenium runs on VBscript. There are some global statements that are used from SQL one of the statements is the sorted procedure. The advantage of Sorted procedure is that it can minimize work and it can decrise the amount of time it requires for testing by preventing reniventing the wheel. SQL have more capabilities available, which makes it helpful tool when we have to verify data.If we use these methods we can get better testing results.
