What is Manual testing?
Manual Testing is a type of Software Testing where Testers manually execute test cases without using any automation tools. Manual Testing is the most primitive of all testing types and helps find bugs in the software system.

Software testing ppt Heritage Institute Of Tech,India. SOFTWARE TESTING TOOLS Softwarecentral. System testing. Explores and identifies the main issues, concepts, principles and evolution of software testing, including software quality engineering and testing concepts, test data generation, test deployment analysis, and software test management This book examines the principles, concepts, and processes that are fundamental to the software testing function.
Any new application must be manually tested before its testing can be automated. Manual Testing requires more effort but is necessary to check automation feasibility.
Principle 5: Manual and automatic test cases. An effective testing process must include both manually and automatically produced test cases. •Manual tests take advantage of the tester's domain knowledge to do more in-depth testing. •Automatic tests take advantage of tireless machines to do more testing than humans can. • To the novice, the test script is the whole tour. The tester goes through the script, start to finish, and thinks he’s seen what there is to see. • To the experienced tester, the test script is a tour bus. When she sees something interesting, she stops the bus and takes a closer look. • One problem with a bus trip.
Manual Testing does not require knowledge of any testing tool.
One of the Software Testing Fundamental is '100% Automation is not possible'.
This makes Manual Testing imperative.
Goal of Manual Testing
The key concept of manual testing is to ensure that the application is error free and it is working in conformance to the specified functional requirements.
Test Suites or cases, are designed during the testing phase and should have 100% test coverage.
It also makes sure that reported defects are fixed by developers and re-testing has been performed by testers on the fixed defects.
Basically, this testing checks the quality of the system and delivers bug-free product to the customer.
Types of Manual Testing:
Below given diagram depicts Manual Testing Types. In fact, any type of software testing type can be executed both manually as well using an automation tool.

- Integration Testing
- Acceptance Testing
Basic Software Testing Concepts
How to perform Manual Testing
- Read and understand the software project documentation/guides. Also, study the Application Under Test (AUT) if available.
- Draft Test cases that cover all the requirements mentioned in the documentation.
- Review and baseline the test cases with Team Lead, Client (as applicable)
- Execute the test cases on the AUT
- Report bugs.
- Once bugs are fixed, again execute the failing test cases to verify they pass.
Myths of Manual Testing
Following are few common myths and facts related to testing:
Myth: Anyone can do manual testing
Fact: Testing requires many skill sets
Myth: Testing ensures 100% Defect free product
Fact: Testing attempts to find as many defects as possible. Identifying all possible defects is impossible.
Myth: Automated testing is more powerful than manual testing
Fact: 100% test automation cannot be done. Manual Testing is also essential.
Myth: Testing is easy
Fact: Testing can be extremely challenging. Testing an application for possible use cases with minimum test cases requires high analytical skills.
Manual Testing vs Automation Testing
Manual Testing | Automated Testing |
---|---|
Manual testing requires human intervention for test execution. | Automation Testing is use of tools to execute test cases |
Manual testing will require skilled labour, long time & will imply high costs. | Automation Testing saves time, cost and manpower. Once recorded, it's easier to run an automated test suite |
Any type of application can be tested manually, certain testing types like ad-hoc and monkey testing are more suited for manual execution. | Automated testing is recommended only for stable systems and is mostly used for Regression Testing |
Manual testing can become repetitive and boring. | The boring part of executing same test cases time and again is handled by automation software in Automation Testing. |
Tools to Automate Manual Testing
Conclusion
Manual testing is an activity where the tester needs to be very patient, creative & open minded.
They need to think and act with an End User perspective.
A file with the JPG or JPEG file extension (both pronounced 'jay-peg') is a JPEG Image file. The reason some JPEG Image files use the .JPG file extension versus .JPEG is explained below, but no matter the extension, they are both the exact same file format.
JPG files are widely used because the compression algorithm significantly reduces the size of the file, which makes it ideal for sharing, storing and displaying on websites. However, this JPEG compression also reduces the quality of the image, which might be noticeable if it's highly compressed.
Some JPEG Image files use the .JPE file extension but that's not very common. JFIF files are JPEG File Interchange Format files that also use JPEG compression but aren't as popular as JPG files.
How to Open a JPG/JPEG File
JPG files are supported by all image viewers and editors. It's the most widely accepted image format.
You can open JPG files with your web browsers like Chrome or Firefox (drag local JPG files onto the browser window) or built-in Microsoft programs like Paint, Microsoft Windows Photos and Microsoft Windows Photo Viewer. If you're on a Mac, Apple Preview and Apple Photos can open the JPG file.
Adobe Photoshop, GIMP and basically any other program that views images, including online services like Google Drive, support JPG files too.
Mobile devices provide support for opening JPG files too, which means you can view them in your email and through text messages without needing a specific JPG viewing app.
Some programs might not recognize an image as a JPEG Image file unless it has the proper file extension that the program is looking for. For example, some basic image editors and viewers will only open .JPG files and will not know that the .JPEG file you have is the same thing. In those instances, you can just rename the file to have the file extension that the program understands.

Some file formats use file extensions that look like .JPG files but are in fact unrelated. Examples include JPR (JBuilder Project or Fugawi Projection), JPS (Stereo JPEG Image or Akeeba Backup Archive) and JPGW (JPEG World).
How to Convert a JPG/JPEG File
There are two main ways to convert JPG files. You can either use the image viewer/editor to save it to a new format (assuming that function is supported) or plug the JPG file into an image converter program.
For example, FileZigZag is an online JPG converter that can save the file to a number of other formats including PNG, TIF/TIFF, GIF, BMP, DPX, TGA, PCX, and YUV.
You can even convert JPG files to an MS Word format like DOCX or DOC with Zamzar, which is like FileZigZag in that it converts the JPG file online. It also saves JPG to ICO, PS, PDF, and WEBP, among other formats.
If you just want to insert a JPG file into a Word document, you don't have to convert the file to an MS Word file format. In fact, a conversation like that doesn't make for a very well-formatted document. Instead, use Word's built-in INSERT > Pictures menu to plug the JPG directly into the document even if you already have text in there.
Open the JPG file in Microsoft Paint and use the File > Save as menu to convert it to BMP, DIB, PNG, TIFF, etc. The other JPG viewers and editors mentioned above support similar menu options and output file formats.

Using the Convertio website is one way to convert JPG to EPS if you want the image file to be in that format. If that doesn't work, you can try AConvert.com.
Is .JPG the Same as .JPEG?
Wondering what the difference is between JPEG and JPG? The file formats are identical but one has an extra letter in there. Really... that's the only difference.
Both JPG and JPEG represent an image format supported by the Joint Photographic Experts Group and have the exact same meaning. The reason for the different file extensions has to do with early versions of Windows not accepting the longer extension.
Like HTM and HTML files, when the JPEG format was first introduced, the official file extension was JPEG (with four letters). However, Windows had a requirement at that time that all file extensions could not exceed three letters, which is why .JPG was used for the exact same format. Mac computers, however, did not have such a limitation.
Basic Software Testing Concepts
What happened was that both file extensions were used on both systems and then Windows changed their requirements to accept longer file extensions, but JPG was still being used. Therefore, both JPG and JPEG files circulated and continue to be created.

While both file extensions exist, the formats are the exact same and either can be renamed to the other without a loss in functionality.
