WHAT IS AUTOMATION TESTING?

Automation testing involves usage of automation testing tools, software and scripts to execute your test case suite. It differs from manual testing, wherein the test engineer has to manually execute the suite.

BENEFITS OF AUTOMATION TESTING

  • Faster execution- Automated testing is comparatively faster than manual testing. Also, it greatly reduces the testing time of upgraded versions of the given product.
  • Cost effective- As mentioned before, test suites may require repeated execution. Since each test suite comprises of thousands of test cases, manual execution would require a lot of manpower, thereby increasing the cost. On the other hand, automated tests get executed quickly and can run unattended.
  • More reliable- Automation testing is more reliable as compared to manual testing as the latter is prone to human error.
  • Repeat-ability- Under manual testing, the test engineer is forced to manually re-execute the previously written test cases while testing an upgraded version of the software, app or website under consideration. As a result, the entire process becomes tedious and time-consuming. Automated testing simplifies the otherwise cumbersome process by automatically replaying the test cases of the unchanged features.
  • Greater flexibility- Automatic playback of previous test cases helps the test engineers to focus upon new and important features.
  • Quick feedback- Faster completion of testing improves the communication of the project team and provides more time to the development team to fix the identified bugs.
  • Faster time to market- Since automation testing shortens the entire testing process; the product gets launched in the market quickly.
  • Increased effectiveness of manual testing- Repetitive, monotonous testing may hamper the creativity and enthusiasm of test engineers. Automation testing helps them to contemplate more crucial issues in an innovative manner.
  • Increased test coverage- Due to constant improvements in automation tools, automation testing has a higher test coverage, covering more features of every new version of the software.

Automation testing has become more popular than its manual substitute due to the ease, efficiency and precision offered by it. Its effectiveness in detecting software bugs has added more credibility to the entire process of testing.

Set Top Box (STB)/or Set Top Unit (STB/STU) Overview

Before starting the introduction of the “Testing” part let’s just understand the basics.

What is a Set Top Box?

A set-top box is a hardware device that receives, decode and display the digital signals on a television. The signal can be a television signal or Internet data and is received by cable or telephone connection. They can have one way which actually means that end user can not interact or modify the channels and two way communications allowing for interactive features like for the end user that they can control or choose what they want on their televisions or whatever type of system they are using.

STB is an device that contains a tuner which connects to a television and takes inputs in signal that can be named as source signal and converts them into a form that they then can be visible on the television or in other words we can say that the set top box is a hardware system that allows a signal to be received, then decoded and then can be visible on a television. The signal type could be a television signal or Internet data and is received by a cable or telephone connection.

There are five types of televisions in India:

  • Broadcast or OTA(Over the Air) Televisions
  • Unencrypted Satellite (Free to air)
  • Direct to home (DTH)
  • Cable television
  • IPTV (Internet Protocol TV)

Today, most of the STB systems are two-way communication, before elaborating two way communication lets understand the one way communication, as the name itself suggests one way which means you can just see whatever is visible on the screen you cannot alter the channels in the television but at the same place in the two way communication the consumer can choose the services or the channels one wants to see.

The set-top boxes can be classified into the following categories:

Cable Converter Box
It can convert any type of channels broadcast from a cable television service into analog radio-frequency signals on a single VHF channel. This box can covert a non cable ready television to cable-ready television. The least number of these cable converter boxes can also de-scramble the signals to manage many channels that are carrier-controlled and access-restricted.

TV Signal Sources
It includes various signal sources:

  • Ethernet cable
  • Satellite dish
  • DSL connections
  • Coaxial cable
  • Broadband over power line
  • VHF or UHF antenna

Professional Set-Top Box
They are also referred to as integrated receiver/ decoders. They are designed especially for robust field handling and rack mounting environments. These are commonly used in the professional broadcast audio or video industry like news channel companies and include a unique feature for producing uncompressed serial digital interface signals.

Hybrid
The hybrid set top boxes came into existence in the late 2000s and became popular among both pay-TV and free-to-air set-top box businesses. These set top boxes provide the usual TV broadcast from cable, satellite and other providers and mix it with the video output provided over a network and personal multimedia content. They give users a variety of viewing content, eliminating the need for having a separate box for each service.

IPTV
These types of set-top boxes are kind of small computers that allow two-way communication that was explained in the second paragraph, it works on an Internet Protocol network and they decode the streaming media video.

STB Architecture

Customer Premises Equipment (CPE)
Set-top box or computer that receives the cable signals coming from the cable modem termination system (CMTS).

Set-Top Box (STB) – There is equipment named as Customer Premises Equipment (CPE) that can access subscription and pay/per View broadcast television services and interactive TV services. Each set-top box is a member of one or more multicast groups in a DSG (DOCSIS Set-top Gate way) network, which allows the STB to receive the OOB (Out of the band data) messages that are needed to receive the programs they are authorized to view.

Point of Deployment (POD) module – Removable security card that is plugged into a STB to uniquely identify and authenticate the STB, which allows the CA (certificate authority) servers to securely identify the set top box and can determine the received programs and services are the one for which the set top box is authorized.

Conditional Access Server –A server systems that encrypt video programs using Conditional Access (CA) techniques which allow only authorized subscribers to decrypt and view the programs.

STB applications
These applications are software programs such as program guides or image organizers that are processed run within the set top box device

  • Application Platforms

The combination of hardware/software and programs that enable the running of other software programs.

  • Resident Applications

These software programs are stored within an STB and are ready to use.

  • Downloadable Applications

These are software programs that can be transferred into an STB.

STB Testing Approaches

  • Functional / Services Testing
  • Signal (Video/Audio) Quality Testing
  • Interface Testing
  • Performance testing

6 Reasons Why Manual Testing Won’t Replace Automated Testing

There are so many discussions that automation testing is replacing manual testing. A lot of developers & testers in modern era want to look for the help of automation testing to make their lives simple. Test automation has received interest and much attention in recent times. But, the truth is that you can’t expect automation testing to execute all the work done by a software tester. A lot of developers and testers in the modern era prefer to seek the assistance of test automation to make their testing easy. However, test automation doesn’t have the capability to completely replace manual software testing. Therefore, we cannot expect that automation testing is stealing the job of software testers out there in the software testing world.

Reasons Why Test Automation will never replace Manual Testing:

  • It only tests what is predictable- Automated tests assure people that what we anticipate to happen does, in fact, turn out. We name this the “happy path”. Automation testing concentrates on functionality that already exists. It isn’t deep but its coverage is enormous. Test Automated is effective for regression tests, precisely when resources are restricted. But only doing test automation is sure to introduce some drawbacks and disappointment in your software testing process.
  • Automation is excessively expensive for small testing projects- Not just do you have automation testing software to pay for, but you also have high maintenance and management related costs, because of script writing & rewriting, including arrangement, set up and processing times. For big and long term projects, the higher expenses can be worth it. But for small and short projects it’s a massive waste of both money and time. When estimating the potential ROI for an automation purchase, you have to factor in additional man hours, too.
  • Automating usability tests is just impossible- Usability testing cannot be automated and it necessitates a human. You cannot train a system (laptop, computer, etc.) to spot “good” usability vs. “bad” usability. Perhaps you might think like, “Ok, we can easily skip usability testing”. Do not make such type of mistake. By skipping this type of testing, you are introducing an incredible amount of threat. This step in the Quality Assurance process is vital to ensure confidence in the product release. There is no means around involving manual testers in usability testing.
  • Automation Testing can contain faults/ bugs- Just like your app’s code can have bugs, automated tests can too. Automation tests can also catch Issues that are unaware of. If you write tests with bugs, you are literally going to have false positives, which can lead to several threats and problems for your clientele and your team. The human element of manual testing can spot these errors and ensure you are testing appropriately.
  • In agile, testing scripts have to be rewritten – Working with continuous feedback in agile environs means fluid changes to the flow of the product, the User Interface, or even attributes. And nearly every time, a modification entails a rewrite of the automated scripts for the subsequent sprint. Fresh new modifications also affect the testing scripts for regression tests, so even that classic automation example necessitates a lot of updates in agile.
  • Technical limits can come into play- The number of test scenarios is complex or downright impossible to automate. The universal argument is “automated testing is cheap”. But it’s not challenging to spend a ton of money and time on elaborate automation. For instance, testing a series of touch screen devices. How do you automate the understanding of a “swipe“and a “tap”. You cannot do that in a way that is equivalent to human being usage.

Final Verdict

The existence of both automated testing and manual testing forces us to think about our option of tools, their charge, and the rewards they will provide. There are a place and time for both testing techniques. Manual testing helps us understand the complete problem and explore other tests angles with flexibility. Test automation helps save time in the long run by achieving a large number of surface level tests in a limited time. It is up to you to decide where and when every single method of testing is used. Even though automation would not replace forms of manual testing, yet neither will manual testing remove automation. Once the distinction between them is understood, the in-depth dread of automation breaks down and a competent, gainful coordinated attempt rises.
