Seeming and sounding so very similar to each other, below are the most commonly used terms in the software testing parlance along with their differences. All in an attempt to clarify doubts concerning these technical terms, the details of these testing techniques come under their respective headings; pairing one term with another.
Let us now look at the pairs along with the differences between them.
Test Plan and Test Strategy
First and foremost, let us focus on defining the two closely resembling terms; Test Plan and Test Strategy.
What is a Test Plan?
A test plan is a deliverable, enlisting all the activities that make up a complete Quality Assurance project. It is a plan that is chalked out by a testing lead or test manager. The plan is a record of the various testing activities supported by their schedules. Included in this exhaustive document are all the details which answer questions centering around “what”, “when”, “how” and “who”.
The Test Plan which emerges as part of the Software Requirement Specification (SRS), clearly indicates what should be tested, when should the test be run, how should the test be conducted and who will be the tester responsible to carry out the test.
Components of a Test Plan:
What makes up a Test Strategy?
While the word plan and strategy are used interchangeably, there is a difference between them when it concerns the process of testing. While both are tagged as methods to achieve a pre-defined goal, a test plan is different from a test strategy.
A test strategy is a rough draft of the testing approach. Identified as a subset of the Test Plan, a test strategy is a high-level and static document that highlights the method of testing that will be implemented. This is derived from the Business Requirement Specification (BRS).
Components of a Test Strategy:
What about Test Scenario and Test Condition?
Simply put, a test scenario is a method in which an application can be tested. On the flip side, a test condition enlists all the specifications a tester should adhere to, as part of testing an application or functionality. That means, there can be multiple test conditions in a single test scenario.
If you are keen to understand the difference between these two terms, the following explanation clarifies all your doubts.
Test Script and Test Case
Test Script – The Detailed Story
The word “script” can be linked to a story which narrates a descriptive account of all the incidents that take place between different characters. So is the case with a test script. Tagged as a detailed description of a test, the test script includes a series of minute details of all the various actions along with data requirements that are essential to carry out the test. Typically presented in the form of a “line-by-line” description, the test script is a step-wise documentation of the manner in which the software program can be used. Details about which buttons to tap and their serial order to be able to perform a pre-defined function are enlisted.
Coming as a leading light, a test script to a new tester is a handy tool that will help him understand the product details better while also introducing him to business domain specifics. Allowing you to follow all the instructions, it is through a test script that you will be able to meet all the specifications of the test idea to complete the testing procedure.
A test case describes a specific functionality that should be tested. It is also important to note that the test case does not include a detailed explanation of the various steps that need to be taken or the information that will come handy to complete the test. Without enlisting any mandatory pre-requisites, a test case certainly gives you a free hand. Allowing you to apply your instincts, it is through this discretion that you will be in total control of what exactly needs to be done to complete the test.
However, this freedom can be of utmost help to the testers who are conversant with the details of the software along with the risks that come with its functionalities. If a tester lacks this basic understanding, a test case may prove to be dysfunctional.
