Test Cases

The project involved adding code from BidiCharacterTest.txt and BidiTest.txt so as to ensure that the implementation of the unicode-bidi algorithm always conforms to the specifications defined in the Unicode Bidirectional algorithm. However as part of the initial steps, we did add a few manual test cases that would check for conformance to some of the major steps. Here are some of those test cases:

• Check for LTR by passing the level number
• Check for RTL by passing the level number
• Check for removal of characters according to the Rule X9 of the algorithm
• Check for non removal of characters according to the Rule X9 of the algorithm
• Check for reordering of characters in accordance with the following types of characters:
  • Weak LTR
  • Strong LTR
  • Strong RTL
  • Neutral characters
  • RTL(Explicit Right-To-Left) Markers (Failing Test Case. The steps to implement this was not implemented till that point in time.)
