The pre-requisites to run Selenium RC tests with Junit:
1) Jre 1.5 or better version needs to be installed
2) /jre/bin folder must be added in environment variable "path"
3) Junit folder path must be added to path or build path in eclipse
4) Selenium Java Client drivers needs to be added to the path for execution

The procedure followed to run the Selenium RC Server is:
1. Open the command prompt.
2. Change the folder path to Selenium RC Server
3. Issue the command "java -jar selenium-server.jar"

You can run the selenium commands in RC slow motion by two ways:
selenium.setSpeed
thread.sleep

1) Download eclipse.
2) Open eclipse -> Workspace Launcher window will open
3) Create a workspace by giving meaningful name
3) Click on Workbench
4) Create a project of type java
5) Create a package under src folder of the package
6) Add Junit to the build path
7) Add selenium rc java client driver to the build path
8) Now drag and drop your test script (.which is exported from Selenium IDE) to the package created

selenium.setSpeed
1. takes a single argument in string format
ex: selenium.setSpeed("2000") - will wait for 2 seconds
2. Runs each command in after setSpeed delay by the number of milliseconds mentioned in setSpeed.
thread.sleep
1. takes a single argument in integer format
ex: thread.sleep(2000) - will wait for 2 seconds
2. Waits for only once at the command given at sleep.

SeleneseTestCase is the class which is having
1. assertTrue
2. verifyTrue
3. assertEquals
4. verifyEquals
We use SeleneseTestCase class to extend the selenium test class file.
For Ex: the test class is declared as follows
public class BookFlightSel1 extends SeleneseTestCase
In the above example SeleneseTestCase is the base class and BookFlightSel1 is the derived class. So, we can directly call and use the parent class methods verify and assert without instantiating the class in BookFlightSel1 class.

The annotations generated with JUnit 4 tests in Selenium are:
1. @Before public void method() - Will perform the method() before each test. This method can prepare the test
2. @Test public void method() - Annotation @Test identifies that this method is a test method.environment, e.g. read input data, initialize the class)
3. @After public void method() - Test method must start with test@Before - this annotation is used for executing a method before.

The challenges with Selenium RC test suites when running in JUnit
1. Each test case of Selenium RC test will invoke the browser and closes after playing back
2. All the Test cases cannot run on a single browser session
3. If there is any dependency between the test cases, it is very difficult to execute
4. Running the test suites in junit will be helpful for only independent test cases.
Note: The dependent test case related issues can be addressed by using TestNG with junit

The basic annotations used to run TestNG tests in Selenium RC:
1. @BeforeClass: The annotated method with @BeforeClass will be run before the first test method in the current class is invoked.
2. @AfterClass: The annotated method with @AfterClass will be run after all the test methods in the current class have been run.
3. @BeforeMethod: The annotated method with @BeforeMethod will be run before each test method.
4. @AfterMethod: The annotated method with @AfterMethod will be run after each test method.
5. @Test: Marks a class or a method @Test with as part of the test.

The @Test should be followed by (dependsOnMethods = "testLogin")
Note:- The test case will be executed after the testLogin case
Ex: @Test(dependsOnMethods = "testLogin")
