To be a professional programmer, there are many things that we have to do to be a good one. In this article, we’ll look at what to do when we’re late, and why we need test-driven development.
Most of us will be late for something eventually. We may be late for various reasons, like not getting enough time for estimates. To manage lateness, we should tell everyone that we might be late- we shouldn’t give people hope and then disappoint them.
If we’re going to miss a deadline, then we shouldn’t rely on hope to get it done. Rather, we must have a fallback plan to deal with being behind. If people try to force us to change the estimate, we must stick with our estimate. We just can’t buckle under pressure to try to make the deadline. If we do, the product probably won’t be good and the code is most likely also going to be bad.
It’s impossible to solve problems faster, we get stuck and we probably can’t get faster. Over time this becomes risky. We’ll be tired and burnt out by the end of it if it lasts one. There is just no way to get something done well by rushing it.
Changing the definition of what it means to be “done” also isn’t good. We may want to move on faster by changing the definition of done but it is not good to do that. No one wants to see all the real work that actually isn’t done even if we say it is. The easiest way to define being done is to make sure that automated tests pass.
Programming is hard. Therefore, we need all the help that we can get. We can’t just put together some code and hope that it works. Instead, we’ve to design everything into well-organized pieces that don’t depend much on each other as it’s beyond one person’s ability to do it well.
We’ll certainly benefit from another programmer’s help and ideas. This means that we should help each other so that we can make all our lives easier. If they need help, it’s time for us to jump in. We should also accept help from others when we have problems. This way, we also get things done faster and better. Also, we should learn to ask for help- when we’re stuck, it’s time to ask for help.

What do you do when you have lots of free time on your hands? Why not learn test programming strategies and approaches?
When you’re looking for places to learn test programming, Test Automation University has you covered. From API testing through visual validation, you can hone your skills and learn new approaches on TAU.
We introduced five new TAU courses from April through June, and each of them can help you expand your knowledge, learn a new approach, and improve your craft as a test automation engineer. They are:
These courses add to the other three courses we introduced in January through March 2020:
Each of these courses can give you a new set of skills.
Let’s look at each in a little detail.
“Appium is an open-source tool for automating native, web, and hybrid applications on different platforms.”
In the introduction, Orane describes the course parts:
The first chapter, broken into five parts, gets your system ready for the rest of the course. You’ll download and install a Java Developer Kit, a stable version of Node.js, Android Studio and Emulator (for a mobile device emulator), Visual Studio Code for an IDE, Appium Server, and a sample Appium Android Package Kit. If you get into trouble, you can use the Test Automation University Slack channel to get help from Orane. Each subchapter contains the links to get to the proper software. Finally, Orane has you customize your configuration for the course project.
Chapter 2 deals with elements and screen interactions for your app. You can find elements on the page, interact with those elements, and scroll the page to make other elements visible. Orane breaks the chapter into three distinct subchapters so you can become competent with each part of finding, scrolling, and interacting with the app. The quiz comes at the end of the third subchapter.
The remaining chapters each deal with specific bullets listed above: sessions and screen capture, timing, element attributes, and using element states. The final summary chapter ensures you have internalized the key takeaways from the course. Each of these chapters includes its quiz.
When you complete this course successfully, you will have both a certificate of completion and the code infrastructure available on your system to start testing mobile apps using Appium.
Andrew Knight, who blogs as The Automation Panda, teaches the course on Selenium WebDriver with Python. As Andrew points out, Python has become a popular language for test automation. If you don’t know Python at all, he points you to Jess Ingrassellino’s great course, Python for Test Programming, also on Test Automation University.
In the first chapter, Andrew has you write your first test. Not in Python, but Gherkin. If you have never used Gherkin syntax, it helps you structure your tests in pseudocode that you can translate into any language of your choice. Andrew points out that it’s important to write your test steps before you write test code — and Gherkin makes this process straightforward.
The second chapter goes through setting up a pytest, the test framework Andrew uses. He assumes you already have Python 3.8 installed. Depending on your machine, you may need to do some work (Macs come with Python 2.7.16 installed, which is old and won’t work. Andrew also goes through the pip package manager to install pipenv. He gives you a GitHub link to his test code for the project. And, finally, he creates a test using the Gherkin codes as comments to show you how a test runs in pytest.
In the third chapter, you set up Selenium Webdriver to work with specific browsers, then create your test fixture in the pytest. Andrew reminds you to download the appropriate browser driver for the browser you want to test — for example, chromedriver to drive Chrome and geckodriver to drive Firefox. Once you use pipenv to install Selenium, you begin your test fixture. One thing to remember is to call an explicit quit for your webdriver after a test.
Chapter 4 goes through page objects, and how you abstract page object details to simplify your test structure. Chapter 5 goes through element locator structures and how to use these in Python. And, in Chapter 6, Andrew goes through some common webdriver calls and how to use them in your tests. These first six chapters cover the basics of testing with Python and Selenium.
Now that you have the basics down, the final three chapters review some advanced ideas: testing with multiple browsers, handling race conditions, and running your tests in parallel. This course gives you specific skills around Python and Selenium on top of what you can get from the Python for Test Programming course.

Software testing is often underrated when it comes to tight deadlines and deliverables. Developers try to compromise in software testing phases, and this leads to more confusion and client dissatisfaction. A professional software developer is the one who remains calm an ensures that the developed solutions go through proper checks and trouble shooting well before the software is due to be delivered or deployed. There are situations when the software development companies do not have an in-house testing team or lack certain tools and resources. In this case, they use third party software testing companies to complete the process.
Software testing, we all know is a mandatory process that needs to be carried out during, after and beyond the development of any software solution. It helps identify major and minor glitches. Early and regular identification, can help programmers ensure that the finished product is error free. Imagine, developing a software and deploying it without any testing or quality checks? What would be the result? The answers could be endless and rolling out a software this way could jeopardize an entire software development organization.
The lack of proper and robust software testing is a major problem facing development companies. This can be due to many reasons. So when integrating a successful testing processes into software development, a development company should keep a few things in mind.
Verifying whether software meets the expected parameters. It is not a superficial but an in-depth process
A healthy process involves investigating the product to find any information that is of value to the stakeholders.
Trying to identify problems before software is released to stakeholders
An integral step in software development that is often underrated is constant communication with stakeholders and collaboration to improve the product
It is important to keep these points in mind when searching for a good software testing partner. Getting software testing done by a third-party vendor is not an easy task because it can be hard to determine if a company will be a good partner or a bad one. Your knowledge of proper testing and quality assurance processes comes into play here.
Organization is an important step not only in testing but other processes too. When we talk about manual testing, it becomes necessary to create an organized structure to store all the relevant details of the project so that no integral information is lost or missed. The stored information and communication details are helpful when creating a successful testing strategy and revisiting information exchanged earlier.
Writing detailed bug reports
Bug reports submitted by the tester are of the utmost importance because these reports contain reports of genuine issue in the application. A detailed report is a great benefit to developers because they can just go through it and see what needs to be done next. If the bug report is not clear or it is incomplete, it creates confusion and may lead to misunderstandings or delayed delivery dates.
Clarity in test cases
The optimal size for a test case is 3 to 8 steps. Clarity in test cases can determine the efficiency in your testing tasks. Just like a detailed bug report is important similarly clear and precise test cases are required to carry out and effective testing process. Test cases should not be very long, the longer the test case the trickier it will be for the developer to work through it.
Besides clear case studies and complete bug reports, the tester must have ability to be focused and stay positive while testing the software application. These features enhance the testing process and make it more reliable.
Where manual testing is considered a priority in a software development process, automated testing aids the process and makes it more effective.
Selenium is an automated testing tool that runs on various OS systems like Linux, Windows, and iOS. It is a testing framework to perform web application testing. Selenium helps the testers to write tests in various programming languages like Java, PHP, C#, Python, Groovy, Ruby, and Perl. It provides a record and review of the features. These records are easy to learn and utilize. Selenium proudly supports some of the largest browser vendors. Major browsers often include Selenium as a native part of their browser. Selenium is undoubtedly the base for most of the other software testing tools in general.

Software testing is the whole and sole process in which the application’s actual working state can be diagnosed. Some software development organizations get it done in house whereas, some require outsourcing. Software testing is a vast topic and its process vary from organization to organization. But it is a critical step and should be carried out by any reliable team.

The shift towards microservices and modular applications makes testing more important and more challenging at the same time. You have to make sure that the microservices running in containers perform well and as intended, but you can no longer rely on conventional testing strategies to get the job done.
This is where new testing approaches are needed. Testing your microservices applications require the right approach, a suitable set of tools, and immense attention to details. This article will guide you through the process of testing your microservices and talk about the challenges you will have to overcome along the way. Let’s get started, shall we?
Traditionally, testing a monolith application meant configuring a test environment and setting up all of the application components in a way that matched the production environment. It took time to set up the testing environment, and there were a lot of complexities around the process.
Testing also requires the application to run in full. It is not possible to test monolith apps on a per-component basis, mainly because there is usually a base code that ties everything together, and the app is designed to run as a complete app to work properly.
Microservices running in containers offer one particular advantage: universal compatibility. You don’t have to match the testing environment with the deployment architecture exactly, and you can get away with testing individual components rather than the full app in some situations.
Of course, you will have to embrace the new cloud-native approach across the pipeline. Rather than creating critical dependencies between microservices, you need to treat each one as a semi-independent module.
The only monolith or centralized portion of the application is the database, but this too is an easy challenge to overcome. As long as you have a persistent database running on your test environment, you can perform tests at any time.
Keep in mind that there are additional things to focus on when testing microservices.
Test containers are the method of choice for many developers. Unlike monolith apps, which lets you use stubs and mocks for testing, microservices need to be tested in test containers. Many CI/CD pipelines actually integrate production microservices as part of the testing process.
As mentioned before, there are many ways to test microservices effectively, but the one approach that developers now use reliably is contract testing. Loosely coupled microservices can be tested in an effective and efficient way using contract testing, mainly because this testing approach focuses on contracts; in other words, it focuses on how components or microservices communicate with each other.
Syntax and semantics construct how components communicate with each other. By defining syntax and semantics in a standardized way and testing microservices based on their ability to generate the right message formats and meet behavioral expectations, you can rest assured knowing that the microservices will behave as intended when deployed.

Testing complex banking applications require extra care and focus on other testing types such as database testing, security testing, performance testing. Functional testing checks whether the features have been implemented as per the requirements or not, but this is not enough. The team needs to test the database of the application for its integrity, validity, and updates.
The testing team should have in-depth knowledge of SQL queries, stored procedures, and other database tools. Another important testing is security testing; in this testing, the team should ensure that the application has proper mechanisms in place to handle data breaches, to manage authentication and authorization of users, etc. In performance testing, the team should make sure that the application can handle multiple users and their actions simultaneously.
