How enterprise mobile apps demand a new approach to development

Mobile application development is important for oragnisations looking for better connectivity with customers,employers and partners. This is a good source of maximizing existing resources and systems. The problem now is, the demand for talented mobile app developers has gone up majorly, while for a mobile strategy to be truly effective, organisations need to change their approach.
This surge in mobile app development is reflected by a recent 451 Research survey indicating that more than half of companies planned to increase mobile budget in 2015. But the problem discussed above will not be solved by just hiring more developers as it isnt as simple as creating new team from the existing IT department.
Front-end mobile app development is different from coding enterprise applications and isn't for everyone. A simple guide to app development.
Here is my simple guide to app development
1. Recruitment
The first step in setting up an agile and customer facing environment is to pick the team members that have the ability and passion to thrive in such an environment.
The team should not be very large as there is no need for a project manager. Developers work closely with the clients and can self- manage the projects.This is not a very comfortable environment going by the traditional IT way.
IT needs to adopt a two track approach that supports agility but also sustains the stability of core IT.
2. Funding
Mobile apps can often be identified, scoped, coded and delivered in a matter of days. Even the most complex apps can be made and delivered with a couple of months of development. The team should not waste time on cost benefits and funding as this will only hamper the timelines for delivery.
The team should focus on picking up flexible projects that deliver as many business benefits as possible and as fast as possible.
3. Focus on real customer needs
Mobile app development companies are targeting customer specific needs. They should focus on what client wants and needs and not just what the company can offer.
Here is a chance to change things and provide solutions that much better match what the business needs. Mobile devices come with a plethora of new tools, coloured high-res displays, cameras, GPS capture and touch-screen manipulation. Many of the best solutions will use these to enhance the user experience.
4. Multiple device support
A mobile solution should not be limited to working on a specific high end consumer device.Use hybrid programming techniques and codes as they are portable in the sense that it can run on either of the platform.
Be careful of standardizing on any one device. This is especially true if taking advantage of cheaper consumer devices. Though often more powerful and feature-rich, they can quickly become obsolete.

All About Web Testing!

What is Web Testing?
Web testing is checking your web application for potential bugs before the website is launched and made live.During this stage the issue of web application security, the functioning of the site, its access to handicapped as well as regular users and its ability to handle traffic is checked.
Web Application Testing Checklist:
The following testing types may be performed depending on your web testing requirements.
1. Functionality Testing:
To check whether your product is as per the specifications you intended for it as well as the functional requirements drafted out while documenting.
Testing Activities Include:
Test whether all the links in your webpage are working correctly and make sure there are no broken links. Links to be checked will include -
  • Outgoing links
  • Internal links
  • Anchor Links
  • Mail to Links
Test Forms are working as expected including the following
  • Scripting checks on the form are working as expected. For example- if a user does not fill a mandatory field in a form an error message is shown.
  • Check default values are being populated
  • Once submitted, the data in the forms is submitted to a live database or is linked to an working email address
  • Forms are optimally formatted for better readability
Test Cookies
Cookies are small files used by websites to primarily remember active user sessions to avoid logging in every time a user visits a website. Cookie Testing will include
  • Testing cookies (sessions) are deleted either when cache is cleared or when they reach their expiry.
  • Delete cookies (sessions) and test that login credentials are asked for when you next visit the site.
Test HTML and CSS to ensure that search engines can crawl your site easily. This will include
  • Checking for Syntax Errors
  • Readable Colour Schemas
  • Standard Compliance. Ensure standards such W3C, OASIS, IETF, ISO, ECMA, or WS-I are followed.

  • Testing your end - to - end workflow/ business scenarios which takes the user through a series of webpage's to complete.
  • Test negative scenarios as well, such that when a user executes an unexpected step, appropriate error message or help is shown in your web application.
Tools that can be used: QTP, IBM Rational, Selenium

2. Usability testing:
Usability testing is a vital part of any web based project. It can be carried out by testers or a small focus group similar to the target audience of the web application.

Tools that can be used: Chalkmark, Clicktale, Clixpy and Feedback Army

3.Interface Testing:
Three areas to be tested are - Application, Web and Database Server
  • Application: Test whether requests are sent correctly to the Database and output at the client side is displayed correctly. Errors if any must be caught by the application and must be shown to the administrator and not to the end user.
  • Web Server: Web server is handling all application requests without any service denial.
  • Database Server: Make sure the queries which are sent to the database give expected results.
Test system response when connection between the three layers (Application, Web and Database) cannot be established and appropriate message is shown to the end user.
Tools that can be used: AlertFox, Ranorex

4.Database Testing:

  • Test if a crash occurs due to peak load, how does the site recover from such an event
  • Make sure optimization techniques like gzip compression, browser and server side cache enabled to reduce load times
Tools that can be used: Loadrunner, Jmeter

7. Security testing:
Security testing is vital for e-commerce website that store sensitive customer information like credit cards. Testing Activities will include-
  • Test unauthorized access to secure pages should not be permitted
  • Restricted files should not be downloadable without appropriate access

As a Web-tester it’s important to note that web testing is quite a arduous process and you are bound to come across many obstacles. One of the major problems a tester faces is deadline pressure. Everything is always needed yesterday! The number of times the code changes is very taxing. Make sure you plan your work and know what is expected of you. It’s always best to define all the tasks involved in web testing and then create a work chart for accurate estimates and planning.

Mobile app is an easy way of collecting feedback rather than posting it on site. App helps save time of the customers. For example – If we visit a new restaurant and want to write a review for them on zomato then its easier for us to open an app than to go back home and write it on their website.

2.Mobile a necessity:

Software Testing- Problems faced by a Tester

Software Testing has lot of challenges both in manual as well as in automation.
Here are a few problems faced by the tester:

1.Frequent Changes in the application:
Once the development is complete, the developer sends the application to the tester. Based on the application test cases our made.
Further changes in the development are sent to the tester, such frequent changes in development lead to confusion on behalf of the tester as the test cases need to be changed for every change in development which leads to problems in testing.

2.Testing the complete application is not possible:
Testing starts with making number of possible combinations and the application is tested based on these combinations. The problem that arises is that there are numerous combinations that can be made and it is not possible to test the whole application both in manual as well as in automation testing
  • Test every possible input to every variable.
  • Test every possible combination of inputs to every combination of variables.
  • Test every possible sequence through the program.
  • Test every hardware / software configuration, including configurations of servers not under your control.
  • Test every way in which the user might try to use the program.

3.Time Consuming in case of Manual Testing
Manual testing is the process of manually testing software for defects. It requires a tester to play the role of an end user and use most of all features of the application to ensure correct behavior. Each time a test case is made, it has to be tested, which is time consuming.

4. Relationship with developers:
A major challenge for a tester is to have a good relation with the developer as they have to work together on an application therefore handle this relation positively. There are simply hundreds of excuses developers or testers can make when they do not agree on some points.

5.Understanding of Requirements.:
Sometimes testers are responsible for communicating with customers in understanding the requirements. What if the tester fails to understand the requirements? Will he be able to test the application properly? Proper understanding of the requirement is important in order for the tester to make test cases and go ahead with the testing. The requirements also define the type of testing to be done, hence it is an important part, but sometimes it is not clear which confuses the tester. Testers require good listening and understanding capabilities

6.Time constraint:
While working on the test cases, the tester is informed of the application, sign off in 3hours which becomes a problem for the tester as he/she has to make a call on which test to execute first so as to ensure that there are no bugs/fixes to be removed.The tester eventually simply focuses on task completion and not on the test coverage and quality of work. There is a huge list of tasks that you need to complete within specified time.
