4.2 What is a Test Sequence?

A test sequence is a set of test cases, unit or functional (not both), targeted on a single c file. A test sequence is written in the form an Excel sheet listing the following:

  • Global declarations
  • Global code
  • Function tested in each test case
  • Input parameters for each test case
  • Pass or fail criteria for each test case
  • Variable declarations, startup code, and cleanup code for each test case

In addition for the traceability report generation, the following artifacts are also added for each test case:

  • Test case ID
  • Requirements covered by the test case

Each test sequence is converted to the TCF file, which is the actual input to the LDRA tool. Figure 1 shows an example of a test case in the sequence. See Section 10 for more information on how to write test cases.

Each test case in a sequence does the following:

  • Runs any initialization code
  • Configures I/O variables
  • Invokes a single function with specified arguments
  • Captures any return values that are to be checked
  • Captures the value of any I/O variables that are to be checked
  • Runs any custom checks, such as checking execution time
  • Saves the results
  • Runs any cleanup code
