Add log4j logging for a unit test in IntelliJ

In IntelliJ

• Click: Run -> Edit Configuration
• Select your test configuration (or add a new one)
• In VM parameters, add
  -Dlog4j.configuration=file:/C:/dev/config/log4j.xml
  (Or wherever your log4j properties file is)

That’s it. The test should now run with log4j logging (although obviously you need to have the necessary log4j jars available).
This example uses a windows file format, but will work equally well with *nix.

I use this approach for turning on MyBatis logging for individual tests. See here for a basic setup of a log4j.xml file to enable logging with MyBatis.

EasyMock

EasyMock is an open source library for creating, and defining the behavior of, mock objects as part of your unit tests. This article describes how to use EasyMock (v3.0), including its record/playback approach, after setting the context with an brief introduction to unit testing in general and the associated need for mock objects.

Hamcrest Matcher

As a follow up to the Hamcrest post I made yesterday, I wanted to post an example of my own Hamcrest matcher implementation. This matcher tests if a string contains a specified number of substrings.
An example usage could be:

    String sql = "select a,b,c from tableA";
    assertThat(sql, hasNumberOfSubstrings(",", 2));

See the source code below. I have been reading up on OSS licenses recently and decided to release this using the same license as Hamcrest – the new BSD license.

I have also attached a jar which includes the associated unit tests, although you will need the hamcrest-unit-test project to compile, which can be downloaded as part of the hamcrest all-in-one jar.

Selenium talk at SF JUG

I attended another great San Francisco JUG meeting tonight, this time on How to use Selenium with Maven/Ant to automate testing of web apps.

The talk was given by Chris Bedford, from Build Lackey Labs – “Automating the Monkey Work Out and the Quality In!”. Overall, I thought this was a great talk by Chris. He clearly has a huge amount of experience creating automated tests and integrating them with build tools and he gave a well structured, interesting, well delivered presentation. I have posted a copy of Chris’s slides and I think the video will be posted on the SF JUG site at some point, but I have also posted my notes from the presentation below…
