Example of a Stress Testing

Stress Testing is a part of software testing life cycle. Software tester also concern on how they can create, find and test a test case and scenario on executing a stress testing from the references of a product requirements.

Here is a scenario and case:

Scenario: After a user was click a button to submit a data and it was successfully all required text box are correct and accepted in the server, the scenario is, what if the connection is lost from client to the server.

Case: Test if all data that being submitted is being cache or not, or the session is expired or not.

Procedure: Assuming that all required value in the text box is now complete then clicking a button to submit, after submit button is click, unplug the LAN connection in the pc client that connected to the server.

Expected Results: Will, it is only an example of stress testing and it depends on the product requirement if data should be cache or not, or the session expired and should repeat it again all data that inputted or the session will not expired and the session is still alive after re-plug the LAN connection and refresh it again.

Point: The point here is how to execute using a stress testing. The point is the simple idea in a stress testing strategy.

Task Scheduler: Mapping Network Drives

A lot of IT tools that provided from the internet are a key factors to automate a daily task on the running the application about the businesses transactions, windows or linux based application.

Mapping network drive is a system services to access the files from the servers. Mapping network drive has a tools to automatically run the map the network drive when the computer client is start whether log-in is executed or not. But there is a alternative way to map the network drive. Using scheduling tasks of a Windows and a little script code to automate and run the mapping of network drive. Here is the guide on how to do the mapping network drive using Scheduling Tasks and batch file script.

1.]  Here is a sample network drives that need to remap.

192.168.1.2/File-a  - for drive a
192.168.1.3/File-b  - for drive b
192.168.1.4/File-c  - for drive c


2.] Here is the script that will be run on a Windows platform.

a. Open a Notepad, type a script command below and save as task.bat and stored it in Desktop.

net use /delete a:
net use /delete b:
net use /delete c:

net use a: \\192.168.1.2\File-a /user:"" ""
net use b: \\192.168.1.3\File-b /user:"" ""
net use c: \\192.168.1.4\File-c /user:"" ""

exit

b. Meaning of command script.

* Net use /delete, means every time the computer is logoff, restart or shutdown and then open it again, the existing network map drive will be deleted and create another net map drive or re-mounted again.

* Net use - means they connects a computer to a shared resource or disconnects a computer from a shared resource.

* drive a, b, c are the drive that mounted settings from the server.

* The IP address are the server address shared folder.

* File-a, File-b, File-c are name of the shared folder.

* user: " " " ", means no username and password in the shared folder in the server.

* exit, means exit the window.

For more info, go to command and type net help use.

3.] Here is the settings of a Task scheduler and the implementing of script of a mapping drive with a filename task.bat

1. Go to Start menu and type Task Scheduler then click Task Scheduler.
2. Click the Create a Basic Tasks
3. Name a task whatever you want. But in this example, I will name it Netmaptask then click Next
4. In Trigger, click When I Log on, (so everytime the PC client is start on the log-in user, the script will run simultaneously.
5 In Action, click start a Program.
a. In Program/script, type cmd.exe
b. In Add arguments input box, copy this,  /c start /min "" "C:\Desktop\task.bat"
where start the command that the window are minimize during running the scripts.
c. Then Save, then Finish.
6. Restart the computer to test if the settings in Task Scheduler of network map drive is working. The output will create a map network drives.

Like for example, the application that use in a virtualization windows that need to have a multiple users to connect to the server. Virtualization windows application cannot accept the windows updates like KB2984972 and KB3003743. This kind of updates is also concern with the user auto login.  Application like virtualization windows can encountered the error with this updates in Windows. Because it cannot allowed to login the multiple user account to the server if this updates is exists on your system.

When downloading updates, just make it sure to research first the functionality of the updates before to download and install it in your system because it can be a bad thinking that maybe it cause by a virus or malware that is why it cannot run your application but the error is the updates that you've been downloads.

The generation of the games is centralized of the compatibility of hardware specification specialized on graphical processing unit property that will match up on the software platform. Game development team and System Analysts is the major and responsible for the constructions of the development through the software life cycle with using the various tools and framework such as software development kit and for the creation of graphical interface and images with the example of 3D modeling system.
