ngx-charts is an open-source, declarative charting framework for Angular projects to build very simplified yet powerful reporting.
Angular will do all rendering and ngx-charts module supports different chart types like bar charts, pie charts, line charts, heatmap, treemap etc, altogether this combo will be useful for any Angular Data visualization projects.
Implementation of ngx-charts:
Step 1: Build an Angular project – refer https://angular.io/cli
Step 2: refer below screenshot and update app.module.ts
Step 3: refer below screenshot and update app.components.ts
Note: As this project is about ngx-chart implementation, the project build status are are hardcoded in the app.components, however you may have to build express backend code and make api calls to jenkins api to grab the build status and provide to front-end angular when you build a real project.
Step 4: refer below screenshot and update app.components.html
For Pie chart
For bar chart
Step 5: run the project using Angular cli “ng server -o”
Refer below pie chart and bar charts from Angular project using ngx-charts module.
DevOps is the latest Development Methodology where Dev team and Operations team are collaborated for better productivity , Improving the time to market of the product releases etc.
DevOps uses lots of tool like Git for Version controlling , Jenkins for Integrating multiple DevOps tools, helps on better communications between Developers, Testers, Operations team etc. Selenium is another tool used as part of DevOps which is a test automation and Jenkins controls and manages Selenium execution.
Puppet is another DevOps tool used for configuration management. Configuration script will be stored in puppet server and puppet agents on various VMs or target machines will be communicating puppet master. There are build management tools like Maven will be part of DevOps. Nagios is another DevOps tool which monitors systems, servers, infrastructures to make sure the deployed applications are running on production servers without any issues.
For testing specific requirements, Jenkins will help to send notification to Tester when a build is available for testing. Jenkins will trigger the selenium scripts and after execution, the results will be send out to target users including developers, management teams etc.
Jmeter is an open source performance testing tool. Popularity is increasing on this tool now a days as reports can be extended and customized by doing little more programming on it.
Open the DOS command prompt (Flow: click on Start menu, Type cmd).
In DOS screen – Navigate to the <JmeterHome>\bin directory.
Note : for Jmeter components or terminologies refer components
Type Jmeter.bat in the above mentioned command prompt. That will bring the Jmeter application ready for performance testing.
Or click on Jmeter.bat file listed in <JmeterHome>\bin should bring the application.
Creating a Performance test scenario
Thread Group: Thread group is the number of virtual users performing the transaction on application under test.
How to add Thread group?
Right click on the TestPlan
Select Add>Thread Group from the popup.
How we design the user transactions or thread group?
As per below screenshot –
1) The requirement shows that number of threads or user actions needed as 60
2) Ram up time is given as 180 sec
3) This indicates that a delay of 3 sec between transactions are applied.
This will ensure that the 60th thread or user will be starting the action at 180th sec.
Here this example is selected based on user requirement or to verify performance metrics.
How to create Jmeter scripts?
There are two ways
1) Manually adding scripts ( Test plan >> Tread Group >> Add>> Sampler >> HTTP Request )
2) Recording using Jmeter’s HTTP(S) Test Script recorder
How to manually add Jmeter scripts
1 Follow the path : Test plan >> Tread Group >> Add>> Sampler >> HTTP Request as copied in the below screenshot
Below the fields needs to be filled when you write a code,
1) Name: you can give any logical name based on application (e.g Login, Home page etc)
2) Server Name or IP : it’s nothing but the IP of your server or the url name (www.your test site.com or “your test site.com” as example or if you know the IP, provide the IP)
3) Path : is “/sso/auth” in this example screenshot below as the remaining contents in the url after “.com” – if your original site is www.your test site.com/sso/auth
4) Make sure the Method è POST and protocol can be HTTP or HTTPS – which ever protocol is used.
How to record Jmeter scripts
Prior doing that we need to configure browser and learn about the Proxy setup
Jmeter to Application server communication need to be routed thru a browser Proxy for this recording purpose. For that you may need to select the Browser (here we can use Firefox browser”
3) Once this configuration is made – create Recording controller
Path ==> Test plan >> Tread Group >> Add>> Logic Controller >> Recording controller
Recording controller will look like as below:
4) Now add the HTTP(S) Test Script recorder
HTTP(S) Test Script recorder will look like as below:
Also make sure the URL patterns to be included. I need only .html so added as below,
5) Now click on Start button and type on the Firefox browser with input url name and subsequent actions that you want to consider for performance test recording.
Jmeter tutorial on Jmeter components, terminologies etc
1. Thread group – refers the virtual users count applied while performance testing using Jmeter.
How we design the user transactions or thread group?
1) The requirement is given that 60 user transactions needs to be made. And requested for 3 sec interval between transactions
2) Then Ram up time should be set 180 sec. This will fulfill the requirement of 3 sec delay between transactions
3) This will also ensure that the 60th thread or user will be starting the action at 180th sec. ( i.e Ramp up time / number of users – will give you the time interval for each uses to kick off. Total ramp up time will be the total time to start all transactions including the 60th one. Based on the transaction scenario length probably first set of 1 to 50th ones may be finished by this time) – similar articles on Jmeter , script Recording
2. Samplers
Samplers are transaction makers which will let you send transactions.
For e.g HTTP Request sampler is used, it will send HTTP/HTTPS request to the web server. This requests can be manually added or recorded using HTTP(S) Test Script Recorder.
Web embedded resources like CSS, images, java applets, scripts, background images are retrieved by HTTP requests.
Test plan is the container of all the performance test scenarios and components of the particular test in Jmeter. Test plan consists of Thread group , temporary work bench, Samplers, etc.

LoadRunner version 12.53 I am yet to try the trial version of LoadRunner 12.53, However I read the following are some of the features shall be available for users Git integration in VuGen REST step builder editor in VuGen 64-bit replay support in various Java protocols and C Vuser protocol New PCoIP remote access protocol Enhanced SAPUI5 recording in TruClient HTTP Video Streaming (HTML5, HLS) support JSON manipulation APIs Web – HTTP/HTML and Mobile Application – HTTP/HTML protocol unification Linux load generator improvements Enhancements to Java-based protocols etc are main features that I would like to try.. Load balancing testing. Load balancing is a method of balancing the network traffic to make sure network transactions are distributed across all the servers. for e.g if a server fails during heavy applied in them, load balancer will redirect the transactions to remaining servers. Basically Load balance acts as a reverse proxy. During performance testing this feature is tested usually. Performance testing vs Load testing vs Stress testing vs Endurance testing 1. Performance testing – The main purpose of Performance testing is to arrive the benchmark & baseline of the system behavior (e.g response time) under normal/moderate load. This test will help performance engineer to analyse how does the application behave under normal conditions. 2. Load testing – here load will be constantly and steadily increased over a given period of time. i.e the constant load applied for a constant period of time. For example a load of 100 users are applied for 15 min. 3. Stress test – it is meant to push the system beyond the normal load limits or extreme conditions. This test is to make sure the servers don’t crash or what point it crashes. Stress test will verify the breaking point of the system or how much load, system can withstand. For example a load of 100 users are applied for 15 min and then 150 users load is applied for next 15 min. then 200 users load is applied for next 15 min. Verify at what point system stopped to respond. 4. Endurance testing – for easy understanding, I would say it is a “Load testing on extended period” to make sure web servers are performing longer period of time. For example a load of 100 users are applied for 48 hours Note: Once the performance testing is completed successfully, tester can assume the performance requirements are met and he can start load testing. After that Stress testing if required. Load testing tools in the market are 1) HPE LoadRunner is from Hewlett Packard Enterprise. 2) JMeter – Apache JMeter. It is a Java based performance testing tool works on web communication layer (HTTP) Loadrunner components Vuser generator – used for generating Scripts Controller – used for creating and executing scenarios Analyzer – used for analyzing results Performance test analysis can be done real time script execution or post execution Real time script execution analysis 1) Performance Engineer needs a coordination with other teams like Database team, app server team, etc to monitor real time performance on Database server, Application server 2) Database and app server team can let Performance Engineer know the performance results on these servers like resource utilization, fail over server works / load balancing works fine etc. Post script execution analysis 1) Verification on Vuser metrics, Vuser errors, can be validated. 2) Verification Transactions graphs for TPS, response time, hits per second can be reviewed. For additional details please click on click link load testing vs performance testing vs stress testing Performance testing best practices and activities. Performance test analysis. What is Performance test analysis? Performance test analysis can be done real time script execution or post execution Real time script execution analysis 1) Performance Engineer needs a coordination with other teams like Database team, app server team, etc to monitor real time performance on Database server, Application server 2) Database and app server team can let Performance Engineer know the performance results on these servers like resource utilization, fail over server works / load balancing works fine etc. Post script execution analysis 1) Verification on Vuser metrics, Vuser errors, 2) Verification Transactions graphs for TPS, response time, hits per second etc. For additional details please click on click link //dmu.876.myftpupload.com/load-testing-vs-performance-testing-vs-stress-testing/ Performance testing best practices and activities. As first step, Performance Engineer needs to learn the requirements, performance expectations & system architecture. Note: To learn the performance requirements & expectations, SME (Subject matter expert ) or production user can help. This information will help to define performance goals and SLAs Then develop best matching performance test scenarios, approach, define goals (SLAs) & sign off test plan. Note 1: To identify the right performance test scenarios, SME can give some feedback on about the current performance issues in production / live application that he/she is facing. Note 2: You can refer another blog of mine on different types of performance scenarios – click link load testing vs performance testing vs stress testing Now Performance Engineer can developer V– USER scripts and execute the scripts in Controller to generate performance analysis results Note 1: Apart from delivering performance analysis results, Performance Engineer can coordinate with other team to monitor real time performance on Database server, Application server and also make sure load balancing is working fine while stress testing. Some of the e.g. when performance testing is needed for Database upgrade, Application upgrade, Or if user complains that application performance is bad – like page response is not meeting his/her expectations.
HP QTP Basic knowledge required to work on QTP/UFT projects 1. Basic programming knowledge on VB scripting – just to modify the recorded scripts. QTP/UFT allows record/play back, using that application transactions can be recorded and later modified based on requirements. Need to learn usage of functions. Instead of functions, QTP/UFT inbuilt feature “reusable” actions can be used. 2. Looping and Parameterization – Parameterization is required to change the already recorded data. Basically the user id, password, input values to be entered in the AUT. To repeat a transaction, looping is used. For looping “For-Next” , “Do-while” etc are used 3. Object Spy & Object Repository– QTP developer can view the run-time/Application object properties and methods of any object in the application. This is helpful during debug mode and find out Dynamic objects. Object Repository is the place where recorded objects are stored by displaying the object properties and values. QTP developer can do some changes on values – using regular expression as an example to handle Dynamic objects. 4. Import / Export data sheet – This is used for very basic reporting where coding is done to store AUT values, some error validations and input values in QTP datasheet or already imported spreadsheet.

3 Recovery scenarios trigger config 4. Now select the recovery operation.
4 Recovery scenarios trigger operation 5. After recovery operation go to post recovery operation as copied below
5 post Recovery scenarios How to do smart identification in QTP Smart identification is needed when recorded script fails to recognize the application object (it may be due to multiple objects has same properties/values or recorded property value is changed) Smart identification uses additional 2 set of object identification layers (1. Base filter properties 2. Optional filter properties) apart from regular mandatory, assistive properties. 1. To get smart identification enabled – navigate Tools > Object identification. 1 object identification 2. On object identification window – click on configure to add 1. Base filter properties 2. Optional filter properties as shown below. 2 object identification properties Descriptive programming in UFT What is Descriptive Programming? Descriptive programming is a way writing and implementing QTP scripts by avoiding the object repository. Usually Non – Descriptive programming access this object repository, where the required object’s properties and values are stored, and execute the scripts. While in Descriptive programming, the object properties and values are directly written in the code so no need to access the object repository while script execution time. For example. If QTP script needs to close a browser the following descriptive program can be used and it can close any single open browse no matter what is the content or name of the browser. Browser(“micClass:=Browser”).close What are the common ways that the Descriptive Programming scripts can be written? 1. Static Descriptive Programming Here the object properties and values are directly written in the code assuming that we know the expected properties and values. For example. If scripts wanted to input user name and password and click ok button to login to an application. Browser(“micClass:=Browser”).Page(“micClass:=Page”).WebEdit(“type:=text”,”name:=username”).set “– USERNAME” Browser(“micClass:=Browser”).Page(“micClass:=Page”).WebEdit(“type:=text”,”name:=password”).set “PASSWORD” Browser(“micClass:=Browser”).Page(“micClass:=Page”).WebButton(“type:=Button”,”name:=Login”).set “LOGIN” 2. Dynamic Descriptive Programming Here the object properties and values collections are created and used while scrip execution time ‘ this is to declare the object variable Dim oDesc ‘to create an blank description Set oDesc = Description.Create Now assign values to the blank description in “oDesc” oDesc(“type”).value= “text” oDesc(“name”).value= “username” now implement it in code as below Browser(“micClass:=Browser”).Page(“micClass:=Page”).WebEdit(oDesc).Set “– USERNAME” Note: Dynamic Descriptive Programming is really helpful when you want to handly an array of objects and child objects.
