iii. Instructions to run test:

All tests are written using JUnit 4.

1) Undo-Redo Test:
    Tests the undo redo functionality as described in the guidelines.
    Also implicitly tests forward iteration of logs while performing redo.
2) Buffer Test:
    Tests the buffer manager functionality as described in the guidelines.
    Correctly implements FIFO replacement.
    Also implicitly tests bufferPoolMap.
    
    
To run tests located in ProjectTest.java
Simply run TestRunner.java (make sure JUnit 4.12 and hamcrest core 1.3 is on classpath)

Example Execution:
    java -cp "~(path to junit jar)\junit\4.12\*;~(path to hamcrest jar)\hamcrest-core\1.3\*;..\;." TestRunner

Example Output:

    new transaction: 1
    recovering existing database
    transaction 1 committed
    Undo Redo test passed.
    
    new transaction: 2
    recovering existing database
    transaction 2 committed
    Buffer FIFO test successful.
