How to use Selenium IDE?!

To start with you need to install the needed IDE.
You can refer to How to install Selenium IDE for more information.

This is very useful to automate user actions on a website, automate certain web administration actions, to automate bug reports, create automated test scripts that shows the bug report and attach that script i your bug report so that the developer can view it and see the flow

• Open Firefox
• Click Tools and click Selenium IDE
• Selenium IDE will open

Now I will show you some simple steps how to work with Selenium.

How to Record a test flow?

• When you open the IDE move the corser to the Red button. There you will see 'Now Recording. Click to Stop Recording'
  This means you are ready record.
• Now you can load the web page you want to test and start recording the steps of the flow you want to execute.
  
  What I'll be doing is search Kala's World :) in Google and view How to install Selenium IDE?! post! For that I am doing the following steps.

• Go to Google search
• Type castakai blog
• Click on Kala's World :) link
•  When the blog is loaded click on How to install Selenium IDE?! title
• The post will get displayed

• When you do each of the above steps it will get recorded automatically in the Selenium IDE, one step at a time.

• Click the Red button to stop recording

• Save the Test Case (File > Save As > Give a file name > Click Save)

• In the Table section you can see the saved steps

• The Reference tab gives you the information what those commands in each step do

• The Command column basically shows what action needs to be performed when testing

• Target column shows where exactly that action has to be perform in the web site 

• The Value column shows the value needs to be given to execute the command or some additional information. 

• Selenium IDE saves the test cases as HTML. You can view it by clicking the Source section
  
  
  How to Run a recorded test case/suit?
  
  
• Now lets run the recorded steps.
• You can Click 'Play entire test suit' / 'Play current test case' button to run the whole flow.
• Or click each and every step to run one step at a time.
• There is a slider Fast Slow to adjust the speed of the execution if you want to look in to the steps more clearly. 

• When you run you will see how it is been executed from the Log tab

• Now let's see how this gives an error if there is a wrong step included.

I am going to edit the 3rd step click.

• Click on the step
• Go to the Target field change the name=btnG to name=btn  The step will be changed.

• Now execute the test case again.
• This test should get failed giving the bellow error in the Log tab.

How to stop the test from a particular step?

• Right click on the step you want to stop the test run.

• Select Toggle Breakpoint.

• Now the execution should stop above the step you put the break point.
• And if you want to move forward from that point onwards click Pause/Resume button. Then the remaining steps will be executed.
• If you want to run through the steps after the break point one by one you can click Step button and execute the steps.

How to add more steps to the test case?

• Go to the end of the test case.
• Click on the empty space. 
• Click the Record button.

• Now you can add more steps as you want and save.
• And if you want to add a step to the middle. Right click > Insert New Command

• You can manually write the command without recording.
• For that Right Click on the empty space and select 'Insert New Command'

•  Now you can enter the values you need in the Command, Target, Value fields and add a new step to the test case.

• And if you need help in adding the values to the Target field you can always go to the next step location from your browser.
  Right click and select 'Inspect Element'

• It will show you the information needed about the field, drop down list ..etc.
  You can always use the 'id=' to identify the place you want.

How to enhance the test case by adding documentation?
This helps a user to understand what we do in the test case or may be we can divide the test case in to sections for our benefit or future reference.

• Click on the place where you need to add a comment. Right Click > Insert New Comment

• Now you can add you comments to make it more simple.

• Save after doing the changes.

Hope you got the basic idea how you can use the Selenium IDE! Enjoy the work!

She also has the task of making sure the preparations for the seasons are done in a timely manner. She also greets new arrivals at the Pixie Dust Tree, helps them find their talent, and gives them their names. She might possess every fairy talent..

 

Test scaling Logistic regression (ML classification algorithm) by partitioning data by Histogram [2]

Information about important classes..

Class	Description
GetMinMax.java	Calculate the min max values of each feature
HistogramEnsembler.java	Encapsulate partitioning data through creation of models for each group. Also the model ensembling logic is implemented.
HistogramHelper.java	This calculates the bin number and converting a given coordinate to a bin number.
HistogramTester.java	Analysis of the partitioned data using a Histogram
HistogramTree.java	Allow formulating and manipulation of the histogram.
IHistogramHelper.java	Defines the contract of the histogram.
LogisticRegresionTester.java	Analysis of the logistic regression with full data set.
Metrics.java	Efficiency calculation
RandomPartitionedEnSembler.java	Encapsulate random partitioning data through creation of models for each group. Also the model ensembling logic is implemented.
RandomPartitionTester.java	Analysis of the logistic regression with randomly partitioned data.
TestHistogramHelper.java	This does the unit tests of the HistogramHelper class. It tests the dimensions and the change axis order.
TestHistogramTree.java	This does the unit tests of the HistogramTree class. It tests the neighbouring bins and checks the grops are of equal sizes.

Testing and Evaluation

	Technique Used	Accuracy (%)	Performance
Method 01	Logistic regression with full data set	74.2720201581548	training time : 52s Prediction time: 12s
Method 02	Logistic regression with randomly partitioned data set	74.35145399566024	training time: 2min42s Prediction time: 15s
Method 03	Logistic regression with partitioned data using histogram.	74.36789359939304	training time: 06min07s Prediction time: 12s

Above table is being used to compare three different methods used to run logistic regression.

According to the statistics given in the table in terms of accuracy all three methods shows relatively similar accuracy levels. When comparing training times method 01 shows the best time of 52s whereas method 03 shows worst. however considering the prediction times method 01 and method 03 shows best of 12s.
 

Tinker Bell ❤

Tink is sassy, brave, and beautiful. Although she is initially resistant to becoming a tinker she embraces the identity when she comes to recognize the value of her talent. She is inexperienced, but a good problem solver.

Tinker Bell is a free spirit, she is what she is, says what she says and doesn’t give a care what others may think, and seems happy to tell people they are a silly ass ;)

She does however endear herself to everyone in spite of her jealous ways and spiteful character. She would lay down her life for Peter and finds it difficult to compete with his attention to other adoring female company.

Tinker Bell is jealous of other females, mermaids and Princess Tiger Lily and Wendy.
Her possessiveness is not a good characteristic and will lead to downfall! She can be easily impatient and annoyed, yet she is extremely loyal..
