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
