Software Test Life Cycle

• Requirement Phase

• Testing Phase

• Defect Validation Phase

• Delivery Phase

Project

Prerequisites

Resources Test Environment Documents Tools


Requirement Phase

To Gather Test Requirement from Client

Study client requirement

Prepare project plan & Time Estimation

Approve Test plan from Client


Testing Phase

Upload latest firmware from configuration tool (Clear Case)

Create and execute test script

Debug firmware if required

Analyze actual result with expected result

Update defect in configuration tool (Clear Quest )


Defect Validation Phase

Validate defect resolved by developer

Reject defect if persist after resolved

Communicate with developer for more

information

Closed Validated defects in Clear

Quest.


Delivery Phase

Deliver test script in Clear Case

Deliver test result to client

Conduct project review meeting

SATA Command Testing

Requirement:

Firmware Unit testing of SCSI Primary commands (SPC) and SCSI Block commands (SBC) on SATA

device

Project Highlight:

1105 python script created and tested as a part of SATA commands testing.

User command for CM or command descriptor block (CDB) created to test 32 command set.

Efforts spent on SPC and SBC specification documents to get exact behavior of SATA commands.

Existing user commands and python scripts can be reused to test functionality of SATA commands.

Debug the firmware to find exact location of introduction of bug.

Communication with firmware development team to reproduce the detected bug.

Tested 1000+ python script as a part of SATA command regression testing.

Total 12 number of bugs reported.

100 % coverage to SATA command testing.

Only 3 Resources involved in SATA command testing.


MPI-2 Testing

Requirement:

To test functionality of Message Passing interface ( MPI-2)

specification

Project Highlight:

Total 512 perl script created and tested as a part of MPI-2 testing

Total 14 bugs reported for MPI-2 testing

Only 3 –resources involved for testing

100 % coverage to MPI2- Specification

Project completed and delivered on schedule


ATA Passthrough Testing

Requirement:

To test ATA Passthrough commands on SATA drive.

Project Highlight:

Total 22 ATA Passthrough commands consider for testing from following protocol group

Non data transfer commands

PIO data in commands

PIO Data out commands

DMA Data in Commands

DMA Data out commands

Total 400+ python script are expected in ATA Passthrough testing

10+ defects expected in ATA Passthrough testing

100 % ATA Passthrough specification coverage

Expected 0% schedule variance


StoreLib IR testing

Requirement:
