How to mock the default constructor of the Date class with JMockit?
long time = SystemTime.asMillis(); Calendar calendar = SystemTime.asCalendar(); Date date = SystemTime.asDate();http://stackoverflow.com/questions/4563584/how-to-mock-the-default-constructor-of-the-date-class-with-jmockit
"it's good practice to use a SystemTime abstraction in your java classes. Replace your method calls (System#currentTimeMillis and Calendar#getInstance) and direct construction (new Date()) with static method calls"
Class Mockit; documentation
[[method summary]] http://jmockit.googlecode.com/svn/trunk/www/javadoc/mockit/Mockit.htmlIt appears that I have been finding lots of documentation that contains deprecated calls. Once I get that code working, I need to find out what the current way of doing business is.

There seems to be many ways of using JMockit. This example might hold some clues to understanding how to mock static methods. Other examples seem to indicate there is no difference between mocking static and instance methods. What happens, however, when there is a method with the same name for both static and instance scopes?
Mocking Static Method Calls
public class SweetLittleMock {
// Same signature as static method in real class
public static String doStuff() {
return "SweetLittleMock";
}
}

Another example of mocking static methods.
jmockit, openJDK and UnsatisfiedLinkError
Try adding <jdk6home>/lib/tools.jar to the classpath, before jmockit.jar. If that doesn't solve the problem, passing -javaagent:jmockit.jar as a JVM initialization parameter definitely should.http://t5187.codeinpro.us/q/50813bbe4f1eba38a437e655
The problem I was having got resolved when I 1) specified JUnit 4 (instead of 3.x.x) in my pom.xml and 2) installed the Eclipse plugin for JMockit ("JMockit Eclipse Plug-in"; Help > Eclipse Marketplace > Find).
Getting started with the JMockit Testing Toolkit
If you are developing on JDK 1.5, then make sure that -javaagent:jmockit.jar (with the proper absolute or relative path to jmockit.jar) is passed as an initialization parameter to the JVM when running tests. This standard JVM initialization parameter causes it to load on start-up the "Java agent" that JMockit uses internally for bytecode instrumentation; this is required to work in all standard JVMs since version 1.5, in all OSs. You may have to use this parameter even on a newer JDK 1.6+, if its Attach API implementation is not supported by JMockit: such is the case with the IBM J9 JDK 1.6, the Mac OS X JDKs, and with JDKs for the Solaris OS. If you use TestNG in a JDK 1.6+ environment, JMockit can be initialized in one of three possible ways (apart from use of "-javaagent" indicated above, which can also be used). See this page for details.http://jmockit.googlecode.com/svn-history/r1166/trunk/www/installation.html
Again, installing the Eclipse plug-in did the trick for me.
mockito; simpler & better mocking
[[mockito logo]] http://code.google.com/p/mockito/Looks nice and simple, but this being my first time in a long time of unit testing with Java, I don't want to feel like I'm limiting myself.
What's the best mock framework for Java? [closed]

RDoc documentation
Hyperlinks to the web starting http:, mailto:, ftp:, or www. are recognized. An HTTP url that references an external image file is converted into an inline <IMG..>. Hyperlinks starting 'link:' are assumed to refer to local files whose path is relative to the --op directory. Hyperlinks can also be of the form label[url], in which case the label is used in the displayed text, and url is used as the target.http://rdoc.sourceforge.net/doc/

Java; JTestR (testing Java with Ruby)
Mocks
JtestR bundles the Ruby mocking framework Mocha. This is the mocking framework used for mocking in both Test/Unit and RSpec tests. For several reasons the RSpec way of mocking doesn't fit well with mocking of Java classes. Mocha on the other hand supports this quite easily.http://jtestr.codehaus.org/Mocks
'RSpec' example for JTestR
describe Account do
context "transfering money" do
it "deposits transfer amount to the other account" do
source = Account.new(50, :USD)
target = mock('target account')
target.should_receive(:deposit).with(Money.new(5, :USD))
source.transfer(5, :USD).to(target)
end
it "reduces its balance by the transfer amount" do
source = Account.new(50, :USD)
target = stub('target account')
source.transfer(5, :USD).to(target)
source.balance.should == Money.new(45, :USD)
end
end
end
https://github.com/olabini/jtestr/tree/master/src/ruby/rspec
I've tried to use pure RSpec; I must be missing something, because I can't seem to get it to work. There doesn't seem to be enough documentation handy for me to understand how to "turn on" RSpec for JTestR.
Configuration
rspec The rspec configuration works exactly like the test_unit configuration value. It also has the same :all parameter, for specifying that all tests are RSpec tests.http://jtestr.codehaus.org/Configuration
Supposedly, this is where I configure RSpec to be used for my tests. I get some strange error about the missing method "filenames" when I do.
