JUnit is a unit testing framework for Java applications, including Android apps. It allows developers to thoroughly test code to ensure it works as intended. Some key advantages of JUnit include that it is written in Java so no new language needs to be learned, tests can be run within Eclipse without extra downloads, and it is free to use. Maintaining JUnit tests and code is also relatively easy. The downsides are that developers must write the tests themselves, which takes time, and tests are limited to available devices. The document then provides tutorials and examples for setting up and running basic JUnit tests on an Android project.

History
 Junit is a unit testing tool for Java. Junit can also be used to test
android projects that are written in java, and can be very useful to
make sure your code is correct.
 Website http://junit.org

 Pros
 Written in Java, no need to learn new
language(monkeyrunner)
 Used in eclipse. No need to download anything
new(uiautomatorviewer)
 Test cases are as thorough as you make them, just doesn’t test
for crashes. (monkeytool)
 Cons
 You have to write your own tests, time consuming(pay testers)
 Internal, deploys with .apk (uiautomatorviewer)
 Can only test on devices you have available(utest)

4. JUnit
 Sustainability
 On the Tool’s end, it is a very popular tool and is very
sustainable with new release every few years.
 On the developers end maintain the JUnit code is
easy because it is written in java, and can be easily
ran right in eclipse. Tests are only as thorough as you
make it. The higher coverage you want, the harder it
becomes to maintain.
 Performance
 Great Performance. Again, Tests are as thorough as
you make it. The higher coverage you want, the
harder it becomes to maintain, but the better
performance you will have and the better your code
is tested.
 Pricing
 Free!!!

5. JUnit
Benefit/cost analysis
 Unit testing is a great way to test each function
and make sure your code is stable.
 JUnit is the easiest way to thoroughly test your
code. And is a widely accepted way of testing.
 JUnit is also free, which makes it even more used,
which makes more resources for information on
Junit.

6. JUnit
Compatibility
 Our team will definitely be using JUnit for our
application. Everyone will be able to use it
because it is written in java, which is the same
language we are developing in and everyone
know. There is no extra software to download
comes with android sdk so it can be used by
everyone.
