Abstract

Consistent with the present disclosure, a block of software code or “software code block” that is executed while particular tests are carried out is assigned a software code block identifier, which is associated with test identifiers, which, in turn, identify the tests that were performed. The software code block identifiers and corresponding test identifiers are then stored in a database. When a portion of the software code block is later modified, either by a change to one or more lines of the code or by deleting or adding code, the corresponding software code block identifier is determined or selected, and then used to access the corresponding test identifiers from the database. The test identifiers are then used to generate a report, for example, that lists each test to be performed in order to determine whether the modified software code block operates properly. The above processes of assigning and storing software code block identifiers and test identifiers may be automated, thereby increasing the likelihood that a complete set of correct tests are performed on the modified software code block. As a result, reliability of the software is improved.

Claims (48)

storing a plurality of test identifiers and a plurality of software code block identifiers in a first data base, such that each of the plurality of test identifiers identifies a corresponding one of a plurality of tests and each of the plurality of software code block identifiers being associated with at least one of the plurality of test identifiers, each of the plurality of tests being associated with supplying a plurality of electrical inputs to a processor circuit and detecting a plurality of electrical outputs from the processor circuit when the processor circuit executes a corresponding one of the plurality of software code blocks, each of the plurality of software code block identifiers identifying a corresponding one of a plurality of software code blocks;

changing a portion of one of the plurality of software code blocks;

storing the changed portion of said one of the plurality of software code blocks in one of the first data base and a second data base;

storing information identifying a location of the changed portion in said one of the plurality of software code blocks in one of the first data base and a second data base, the information being a line number corresponding to the location of the changed portion in said one of the plurality of software code blocks;

determining one of the plurality of software code block identifiers associated with said one of the plurality of software code blocks based on the line number;

selecting a group of the plurality of test identifiers based on said one of the plurality of software code block identifiers, the group of the plurality of test identifiers including more than one of the plurality of test identifiers; and

identifying a group of the plurality of tests associated with the selected group of the plurality of test identifiers, the group of the plurality of tests including more than one of the plurality of tests.

2. A method in accordance with claim 1 , further including performing each test of the group of the plurality of tests.

3. A method in accordance with claim 1 , further including:

generating a report that lists the identified group of the plurality of tests.

4. A method in accordance with claim 1 , further including storing, in the data base, data associated with the detected plurality of electrical outputs associated with said each of the plurality of tests.

5. A method in accordance with claim 1 , wherein the software code blocks include network element software.

6. A method in accordance with claim 1 , wherein the software code blocks include network management software.

7. A method in accordance with claim 1 , wherein one of the plurality of tests generates data that includes monitoring information associated with an optical communication system.

8. A method in accordance with claim 1 , wherein said one of the plurality of software code blocks includes a plurality of lines of code, said changing the portion of one of the plurality of software code blocks includes changing at least one of the plurality of lines of code.

9. A non-transitory computer-readable medium storing a computer program for instructing a programmable computer to implement a method of:

storing a plurality of test identifiers and a plurality of software code block identifiers in a data base, such that each of the plurality of test identifiers identifies a corresponding one of a plurality of tests and each of the plurality of software code block identifiers being associated with at least one of the plurality of test identifiers, each of the plurality of tests being associated with supplying a plurality of electrical inputs to a processor circuit and detecting a plurality of electrical outputs from the processor circuit when the processor circuit executes a corresponding one of the plurality of software code blocks, each of the plurality of software code block identifiers identifying a corresponding one of a plurality of software code blocks;

changing a portion of one of the plurality of software code blocks;

storing the changed portion of said one of the plurality of software code blocks in one of the first data base and a second data base;

determining one of the plurality of software code block identifiers associated with said one of the plurality of software code blocks based on the line number;
