After the course, student will be able to: 2017/3/25 Objectives After the course, student will be able to: Understanding the way to create a Test Case Using Test Case checklist to review a Test Case FPT-Software Training Materials

Agenda Design test case Write test case Test case checklist FPT-Software Training Materials

Test Case Detail design Test case SRS Test script Test Plan Test data 2017/3/25 Test Case Test Preparation Detail design SRS Test Plan Test case Test script Test data This slide used to show the input and output of create testing plan FPT-Software Training Materials

Test Script: scripts that use for testing or check the output 2017/3/25 Concepts Test Case: A set of test inputs, execution conditions, and expected results developed for a particular objective, such as to exercise a particular program path or to verify compliance with a specific requirement. Test Script: scripts that use for testing or check the output Test Data: data is using for testing FPT-Software Training Materials

Why Test Case? Design scenario (test conditions) before test execution 2017/3/25 Why Test Case? Design scenario (test conditions) before test execution Predict expected result Help new testers familiar with existing application/system without reading requirement Design test case before execution FPT-Software Training Materials

Good Test Case Has a high probability of finding errors 2017/3/25 Good Test Case Has a high probability of finding errors Clear of purpose Well organized Reviewable Maintainable Useful to other testers Ex: A person visit a doctor because of an overall felling of malaise. If the doctor runs some laboratory tests but do not detect the problem, we do not call the laboratory tests “successful”. They were unsuccessful tests because the patient is still ill, and the patient may question the doctor’s ability as a diagnostician. However, if a laboratory test determines that the patient has a peptic ulcer (loet da da`y), the test is successful because the doctor can now begin the these words in the proper sense. => Similar, of course, is that we should think of the program, as we begin testing it, as the sick patient Questions: What is bad test case?

Design Test Case White Box Testing: Uses specific knowledge of programming code to examine outputs FPT-Software Training Materials

White Box Testing - Example 2017/3/25 White Box Testing - Example Instruction coverage Decision coverage Condition coverage Decision/Condition coverage Multi condition coverage Give trainee material to show the example in White_Black_Box_Test_Example.doc FPT-Software Training Materials

Design Test Case Black Box Testing: Assess how well a program meets its requirements Focusing on testing functional requirements I/P O/P FPT-Software Training Materials

Black Box Testing - Example A large IT company is in the process of revising salary structure for its employees. The salary will be revised on the check point for all employees with at least one year seniority The rule for salary revision are provided below: Check point: 90 -> 100: Increase existing salary by 20% Check point: 80 -> 89: Increase existing salary by 15% Check point: 75 -> 79: Increase existing salary by 10% Check point: < 75: No increase FPT-Software Training Materials

Black Box Testing - Technique 2017/3/25 Black Box Testing - Technique Expand Conditions into Test Cases using Boundary Value Analysis: a minimum or maximum input, internal, or output value specified for a system or component Equivalence Partitioning: one or a few cases are chosen to represent an entire equivalence class Decision Tables Case study Give trainee material to show the example in White_Black_Box_Test_Example.doc FPT-Software Training Materials

Fsoft - Test Case Structure 2017/3/25 Fsoft - Test Case Structure Test case specifications Test procedures Pass/ Fail criteria: List all results that decide test case is passed or failed Dependencies: List all test cases that must be done before performing this case FPT-Software Training Materials

Test Case Specifications 2017/3/25 Test Case Specifications List cases/scenario that will be tested Interface Test with valid data Test with invalid data: Mandatory field Min, Max length Incorrect type, format Boundary, etc FPT-Software Training Materials

Test Procedure Test actions taken by the actor when executing a test case Test input: the actual values input by the actor at each step/action Expected result: the expected response from the application for a given step/action FPT-Software Training Materials

Pass/Fail criteria - Inter-case dependencies 2017/3/25 Pass/Fail criteria - Inter-case dependencies Pass/Fail criteria: List all results that decide test case is passed or failed Inter-case dependencies: List all test cases that must be done before performing this case Inter-case dependencies: login done before execute a function FPT-Software Training Materials

Recorded automatically 2017/3/25 Test Script Recorded automatically Coded manually: using test tools or standard programming languages like VB, C/C++, Java or SQL Test stub: temporary implementation of part of a program for unit test purposes Test driver: program which sets up an environment to call a module (or function) for testing Test scripts may be recorded automatically or coded manually using test tools or standard programming languages like VB, C/C++, Java or SQL FPT-Software Training Materials

Prepare data test for scenarios 2017/3/25 Test Data Prepare data test for scenarios Tools Manual Tool: Data Advance Generator FPT-Software Training Materials

Navigation conditions Validate text fields Validate number fields 2017/3/25 GUI Test Case Aesthetic conditions Navigation conditions Validate text fields Validate number fields Validate date fields Aesthetic Conditions: Screen background, Screen font, location of fields Navigation Conditions: main menu, sub menu, toolbar, tab order, cursor, combo box, radio box, check box Combo box: check LOV (list of values) and the order of LOV FPT-Software Training Materials

GUI Test Case - Validate text fields Check mandatory fields Max length Special characters/htlm tags (name, email, address, password) Space at the beginning and the end of string Full-size, haft-size characters (Japanese) Case-sensitive or not Unicode FPT-Software Training Materials

GUI Test Case - Validate number fields Check mandatory fields Max/Min values Integer/Decimal numbers Positive/Negative numbers Check conversion of format (decimal symbol, digit grouping symbol, display leading zero) Display decimal symbol, digit grouping symbol, leading zero FPT-Software Training Materials

GUI Test Case - Validate date fields 2017/3/25 GUI Test Case - Validate date fields Check mandatory fields Check date format (inputted date, conversion of inputted date) Compare inputted date to current date (if required) Compare dates based on business rules Compare “From Date” to “To Date” Check format date with regional setting FPT-Software Training Materials
