Java basic for Selenium - Selenium Tutorial II


Today we are talking about Array. The software tester should have some basic knowledge about java when writing selenium scripts for the validations.
Array is a data structure where stored in elements in same data type. The declaration and initialization an array as follows.

int[]  Array_a;   or  int  Array_a[]; - This is an integer array.
int[10] = Array_num;  - This is an integer array which stores 10 elements.
Array_num[0] = 10;    - Assign value 10 to 0th element of array. (Index [0])
int[]  Array_num = { 1, 2, 3, 4, 5 }; 

Finding maximum value of an array


Finding minimum value of an array


Finding average value of an array


Find the key of an array


Reverse an array
The time complexity of this algorithm is O(n/2) which is O(N) because we are iterating over array till midpoint only.


The initial iteration is happening as follows

The second and the third iterations are happening after that.
The loop is iterating until the middle index. After reversing first, second and third indexes, no need to iterate 4th and 5th indexes because the reverse has been already completed.Please send your comment  and suggestions..  
See you soon with another selenium tutorial........ 
Thanks,
Dananji Withana

Security Testing - I - Web Testing - I

Security Testing - Web Testing  Security is set of measures to protect an application against unpredictable actions that causes it to terminate functioning. Security testing is a process intended to reveal flaws in the security mechanisms of an information system that protect data and maintain functionality as intended. This is type of non functional testing. For minimizing the defects by identifying threats in the system and cost of quality, the security testing must be started at the early stage of Software development life cycle. The following figure is shown the relation between Software development life cycle and security testing . Test plan should includes Test scenarios and test cases related to the security. Test data related to the security test cases. Test tools for security testing and test outputs on the different test tools Security Testing Approach 1. Identify all the business requirements, security goals ...

Strategies and methods for test case design II

Strategies and methods for test case design Today we are talking about how to get an approach for writing a good test case. Developers cannot prevent or eliminate all the defects raised in the application during implementation. That's why the application should be tested before deliver to the customer. Before starting the execution, we need to identify test scenarios and write test cases for each identified scenarios. Test case is test description which needs to be executed to verify the functionality or feature of the application. A good test case have a good possibility of finding defects. For designing effective test cases, there are two basic strategies that can be used. Black box test strategies White box test strategies Test Strategies Sources Testing Techniques Black Box  Functional requirement specification Equivalence partitioning   Business requirement specification Boundary value analysis   Domain knowledge State Transition Testing     ...
