Software testing refers to a software testing engineer to evaluate a particular software item, look for defects and resolve them. Though it should be performed at the development stage, but is termed as a ‘validation and verification’ process.
The software tester assesses the quality of the software, checking whether the expected output matches the entered input. He should be eager to learn, be innovative and accountable to his tasks, and have excellent programming and communication skills. Speaking of accountability, here are the seven important tasks a tester and working in a manual testing services company should not forget to perform. The tasks are listed out as follow:
1. Show interest in your job
To ensure a good performance, the tester should be alert and ask relevant questions. Asking questions will help clear your doubts, and give you an overall picture of what you have to do. According to your problem, you can ask questions regarding the requirement, the changes in the software, the implementation of the requirement, bug-fixing and relation of the product to development and business.
2. Perform a Document Testing
To a software tester, working with the installation and performance of software day after day might be a daily experience. However, the same might be a heinous task for a first-time user or a layman. They might turn to the user manual for help, but what if it doesn’t help them at all? Customer dissatisfaction can play a huge role in adversely affecting your future sales. Therefore, it is a smart task to religiously test the user and installation guides so that even a first-time user will be able to understand instructions at a go. Even if he has a great product, a not-so-helpful manual won’t satisfy customers.
3. Work as a pair:
As similar to working with a laboratory partner, working with a fellow software tester can actually be beneficial for the product. Even if the concerned tester is a pro at his job with years of experience, working with a similar-minded tester will bring forward fresh ideas, and sometimes ingenious insights regarding how to work with different scenarios and the tried-and-tested techniques of software testing services.
4. Accurate analysis of data
Even after receiving the correct results for the product, the tester still needs to analyze them. He is required to understand the data, analyze them according to the expected outcome of the software item and resolve the issues in the test environment, test data and the bugs that prevent success. The tester also needs good reporting and communication skills, which would be needed in his status report. He would be expected to give a brief but analytic description about the actions taken, the results and how to plan to handle the situation.
5. Fixing bugs
A software tester should be able to priorities his tasks accordingly, and decide upon whether a test should be automated or be tested manually. His job does not end after he reports a bug, but continues even after the developer has fixed them. An important task for the software tester is to actually know the kind of code fix the developer has applied, and how it will affect the software. He should also understand and discuss how the developer fixed the particular bug, and its effects on the product as a whole. If the developer is not able to reproduce the bug, the tester should support him in the same so that the bug can be fixed.

Magneto development services provider will explain plugin system in Magento 2. You will learn the way to use magento 2 plugins from the basics. Read and discover how professionals do it.
You will learn through this article how to use Magento 2 plugins that modify the behavior of all public functions without overloading the PHP class (block, model etc.) the container.
What are plugins?
To avoid having to override a class to modify a simple, Magento 2 plugins provides a mechanism to effectively manage this type of "rewriting" as well as to minimize conflicts between extensions.
To date, plugins can only be used for rewriting public methods and are therefore subject to the following limitations:
1) final methods
2) non-public methods (protected or private)
3) static methods
4) Constructor ( _construct)
5) virtual Types
Magento provides three "types" of different plugins:
1) before: Change the arguments provided to a method
2) around: Change the behavior of a method
3) after: To "rework" the output of a method
Declaration of a plugin
The declaration of any plugin must be done in the file di.xml of your module. This file can be placed, depending on its use, either within the directory etcyour module (plugin to use the backend and frontend) or in etc/frontend
The following can be specified:
1) observer_type: The class name, or virtual interface type you want to observe
2) plugin_name: The name of the plugin (eg. catalog_product_custom_plugin)
3) plugin_type: The name of the class or type used by the virtual module (ex.Vendor\Module\Plugin\ModelNamePlugin)
4) plugin_order: The order in which the plugin will run. Very useful to effectively manage the execution order of several plugins overloading the same method (see "Execution Order" below for details)
5) plugin_disabled: This parameter can be set trueif you want to disable the plugin
Execution order of the plugins
When multiple plugins rewriting the same method exist, the following order of performance will be followed by Magento:
1. The type of plugin beforethat has the highest priority (= the one with the least sortOrder)
2. The type of plugin aroundthat has the highest priority (= the one with the least sortOrder)
3. The other type of plugins beforebased on their priority (from smallest to largest sortOrder)
4. The other type of plugins aroundbased on their priority (from smallest to largest sortOrder)
5. The type of plugin afterthat has the lowest priority (= the one with the largest sortOrder)
6. The other type of plugins afterbased on their priority (largest to smallest sortOrder)
To change the settings passed to a function, it is necessary to create a methodbefore[methodName]in your plugin (which [methodName]corresponds to not the method you want to change, for example SetNamefor a method named setName).
The method created within your plugin parameter must take the class which includes the function you want to change and its various parameters. Example of method overloading setNameclass \Magento\Catalog\Model\Product:
In this example, the product name passed in the argument $namewill be automatically enclosed in parentheses.
As you have probably noticed, the type of plugins beforehave returned an array containing all the parameters of the function.
To change the behavior of a function, a method around[methodName]must be created within your plugin (which [methodName]corresponds to not the method you want to change, for exampleSavefor a method named save).
The method created within your plugin parameter must take the class which includes the function you want to change and a second type parameter \Closurecorresponding to the original method.
Example of method overloading saveclass \Magento\Catalog\Model\Product:
In this example, we execute line 9 will recover the original method and the return value. If it is defined, a third function, called here doSomething, will be executed.
Finally, we return line 13 returning the original method.
To change the return of a function, it is necessary to create a method after[methodName]in your plugin (which [methodName]corresponds to not the method you want to change, for exampleGetNamefor a method named getName).
The method created within your plugin parameter must take the class which includes the function you want to change and a variable $resultthat will contain the result of the original method.
Example of method overloading getNameclass \Magento\Catalog\Model\Product:
In this example, the return of the original method, which is here in the name of the product, will be surrounded by "| ".
