SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – II

SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – II     This blog explains about SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – II . It is explained clearly below :  We have already discussed about Web application testing in the previous blog SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – I  _______________________________________________________________________________                                                              Sample test scenarios for testing a web application Few other considerations to be included while testing a website are given below. What is the expected load on the server (e.g., number of hits per unit time)? What kind of performance is required under each load condition (such as web server response time, database query response times)? What kind of tools will be required for performance testing (such as web load testing tools, other tools already in house that can be adapted, web robot downloading tools, etc.)? Who is the target audience? What kind of browsers will they be using? What kind of connection speeds will they be using? Are they intra-organizations (thus likely with high connection speeds and similar browsers) or Internet-wide (thus with a wide variety of connection speeds and browser types)? What kind of performance is expected from the client side (e.g., how fast should pages appear, how fast should animations, applets, etc. load and run)? What kind of security (firewalls, encryption, passwords, etc.) will be required and what is it expected to do? How can it be tested? How reliable is the site’s Internet connections required to be? And how does that affect the […]

SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – I

SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – I     This blog explains about SOFTWARE TESTING TRAINING IN CHENNAI – WEB APPLICATION TESTING – PART – I . It is explained clearly below :                                               WEB APPLICATION TESTING   INTRODUCTION Web application testing, a software testing technique exclusively adopted to test the applications that are hosted on web in which the application interfaces and other functionalities are tested.                                                                                                                    Functional Testing: This testing is used for checking all the links of the web pages; form testing, cookie testing and database connection. Usability testing :  To verify how the application is easy to use with. Test the navigation and controls. Content checking. Check for user intuition. Interface Testing: This checks if the web server and application server interface, application server and database server interface have proper interaction or not. This test ensures that the users do not see any error messages. Compatibility Testing:  Compatibility Testing is very important as it checks browser compatibility, operating system compatibility, mobile browsing and printing options. Performance Testing:  Performance testing includes web load testing and web stress testing. Web load testing technique checks if many users can access the same page at the same time and whether a web page can handle […]

TRICKY MATHS PUZZLES – WITH ANSWERS – PART – III

TRICKY MATHS PUZZLES – WITH ANSWERS – PART – III This blog explains about TRICKY MATHS PUZZLES – WITH ANSWERS – PART – III . Some of them are given below : We have already discussed about some puzzles in the previous blogs TRICKY MATHS PUZZLES – WITH ANSWERS – PART – I & II . _________________________________________________________________ 1. Two fathers and two sons sat down to eat eggs for breakfast . They ate exactly three eggs, each person had an egg. How is this possible ? ANSWER :  One of the father is a grandfather and other one is a son of the grandfather . So there are actually one grandfather, one father and a grandson      _________________________________________________________________     2.   Three guys rent a hotel room for the night. When they get to the hotel they pay the $$\$30 $$ fee, then go up to their room. Soon the bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep one of the $5 dollars and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend the could not explain the following details: Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip. HOWEVER, 3 • $9 + $2 = $29The guys couldn’t figure out what happened to the other dollar. After all, the three paid out $30 but could only account for $29.  ANSWER  They did NOT spend $9 • 3 + $2. They spent exactly […]

TRICKY MATHS PUZZLES – WITH ANSWERS – PART – II

TRICKY MATHS PUZZLES –  WITH ANSWERS – PART – II Here in this blog we are discussing about TRICKY MATHS PUZZLES –  WITH ANSWERS – PART – II . Some of them are illustrated below :                 We have already discussed about some problems in the previous blog TRICKY MATHS PUZZLES – PART – I .  _______________________________________________________________________   1.   SOLVE THE GIVEN TRICKY QUESTION . GIVEN : The cost of three red balloons = Rs. 21                  The  cost of one red and two pairs of blue balloons = Rs. 31                  The cost of one pair of blue balloons and two orange balloons = Rs. 20                                                                   +              +                      =   21                              +              +                         =    31                               +      +              =   20        +                  x        =   ?                        +             +           =  21   Three red balloons = Rs. 21                    3                =   21  Then the cost of one red balloon = Rs. 7                                          =>           =  7                     +                 +               =  31       Again the cost of one red and two pairs of blue balloons = Rs. 31  Also the cost of one red balloon = Rs. 7  So the cost of two pairs of blue balloons = 31 […]

TRICKY MATHS PUZZLES – PART – I

TRICKY MATHS PUZZLES – PART – I  Here in this blog we are discussing about TRICKY  MATHS  PUZZLES –  PART – I . It is illustrated below : _______________________________________________________________________      1. The bigger circle radius is 4 cm and the medium circle radius is 2 cm . The line tangent to all the circles and the three circles touch each other . Then what is the radius of the smallest circle ?  SOLUTION :   Let the radius of the bigger ( orange ) circle be 4 cm and the medium ( blue ) circle be  2 cm  Here r is the radius of the smaller (red ) circle                                                                                        The distance( X )  between the orange and the red circle will be obtained from having the distances (4 + r) and ( 4 – r ) and the corresponding distance ( Y ) blue and red circles from  ( 2 + r ) and  ( 2 – r  ) By Pythagoras theorem , we have X =  √ ( 4 + r ) 2 –  (  4 – r ) 2       = √  ( 16 + r2 + 8r ) – ( 16 + r2 – 8r )     =  √  8r + 8r    =  √ 16 r  X =  4√ r  Y  =√ ( 2 + r ) 2 – ( 2 – r ) 2      =  √(  4 + r2 + 4r ) – ( 4 + r2 – 4r )        = √ 4r + 4r   =  √8 r   Y    =  2 √2 r    […]
