Wake up, Shake up and then test...

You can't master testing unless you reinvent it

This is how one of the lessons of the book "Lessons learned in Software Testing" goes. And this statement is so very true. Just adding to the above statement based on my experience-

You can't master testing unless you reinvent it and you can't reinvent testing unless you reinvent your thinking

Software Testing is a job that requires extensive thinking. And unlike many people's beliefs - thinking is a skill, something that can be acquired and sharpened always. In order to test an application efficiently, we do need to sharpen our thinking skills and mental routine and apply the renewed thinking to test an application. There are many credible ways by which thinking can be enhanced or sharpened. Some ways include mastering Edward de bono's better thinking principles, studying epistemology, understanding cognitive psychology etc. These are the techniques and studies which can be learnt and applied to enhance one's thinking skills and in turn the efficiency of a tester.

Recently, while reading a book- "Instant Analysis" by David J. Lieberman- i came across a different thought line on how our physical routines can affect our thinking and even our thinking outputs. Life does get monotonous, mechanical and predictable as we move on. For example, as the day passes notice certain day-to-day behaviors-

- Once you get into office, look around your desk- you would probably find that picture on the same place as it has been for months or years, same place for a to-do list, same place where you keep your laptop and work.
- Look at the pattern in which you decide your password. Its probably following the same sequence for as long as you can remember.
- Are you in a habit of keeping your desk or your PC desktop unorganized and cluttered ?

There can be a numerous such examples (based on one’s life style) that you can relate to just by looking around your physical world. Probably the list of things that you have been doing the same way for a long time just because they have been part of your habit, something your subconscious mind drives you to do without you realizing it. As Dr. David puts it-
"You see something and you instantly go into a conditioned state associated with your environment."

The idea here is to be aware of such sub-conscious habits and behavior patterns and take a step forward to break the pattern by shaking up your daily routine. By doing so, it helps to jolt your usual thought patterns and open up new avenues of thinking. And it does work! I have tried this in my daily life and this kind of pattern interrupting exercises actually help to open new pathways in your brain eventually affecting the thinking outputs. Here is what needs to be done -

- Based on your life style, make a note of different aspects of your daily routine.
- Slight change any of the ordinary behaviors (e.g. organize your desk, move the stuff and rearrange, slightly change the order of things you do when you reach office etc.)
- Do things that you usually dont do and vice versa (by slightly adjusting the behavior)

Have more awareness of self and age-old pattern and eventually breaking them introduces you to a new thought process. A thought process that has the potential to bring in new ideas to your work, help you in coming up with new ways of testing.
As Software Testing is a job that requires immense thinking abilities, these slight adjustments to the physical routine has a potential to go a long way to bring in necessary change and freshness in a way you have been approaching testing.
I am quite keen to experiment more with this thought while testing and managing the testing in the time to come.

Uncovering Myths about Globalization Testing- 4

Myth 11: Localization - means Localized product on a localized Operating System, Internationalization- means Localized product on English Operating System

One of the readers of my previous Globalization testing related post had commented the following-
I have always heard the below definitions for L10n and I18n:
Localization - means Localized product on a localized Operating System.
Internationalization- means Localized product on English Operating System.
Could you please clarify. As a person who has not done any such testing, I am always in doubt regarding this.

It made me realize that one of the most misunderstood aspects in the world of Software Globalization is comprehension of terms “Internationalization” and “Localization”. I too used to be having a wrong notion about these terms before I started working in this field. I think the major reason for the incorrect understanding about these terms is the lack of awareness and exposure in the field (particularly in India). Moreover, the available definitions and literature also makes it a bit hard for a person with no background in Software Globalization to fathom the basic differences in Software Internationalization and Localization. So, without delving any deeper into text book definitions of Internationalization and Localization, let me attempt to explain these terms as I have experienced while working in the Industry.

Software Globalization:
At the most basic level, Software Globalization= Software Internationalization + Software Localization.
Simply explained, the term “Globalization” relates to all the activities that are required to conceptualize, design, develop, test, maintain and probably sell and market the product in supported International geographies. Globalization is a superset term which constitutes Software Internationalization and Software Localization. Whenever someone uses the term “Globalization testing”, it primarily includes testing of all the changes that needs to be included into the Software to make it fit to be developed in different languages or technically put- Internationalize it. We will look deeper into the phrase “testing of all the changes” (used in previous sentence) in the following points.

What is Software Internationalization ?:
As we now know, one of the activities that come under Software Globalization umbrella is “Internationalization”. Lets forget about Internationalization testing for a moment and focus our thoughts on “What is Internationalization ?”. The primary thing to keep in mind when we talk about Internationalization is that- Internationalization is a Software Design and Development activity.
One question that comes to mind at this point is- If Internationalization is a Software Design and Development activity then how is it different from Design and Development of base Software product (By base Software product I mean that English language Software assuming the Software gets developed in English language first and then into other languages). Base Software development includes development of all the features and functionalities of the application e.g. Taking an example of Windows Notepad application, Base product development includes- writing code for functionality of File/New, Open, Save, Save-as menu, Edit menu and so on. So base product development ensure that the basic features that a product offers are in place.
So, where does Internationalization come into Picture here ?
When we talk of selling the Software in International market, broadly 2 types of requirements are taken in to consideration
a) The features and functionalities that the base language product offers should be available in International version of the Software (there can of course be some exception e.g. say German market does not need a feature that may be a in demand in US market)
b) International requirements i.e. requirements pertaining to the locale in which the Software is being sold. Consider the following examples-
• For a software being developed for Arabic market, it should provide a provision to write in a Left to Right fashion (as against English- Right to left).
• Traditional Chinese is written from Top to bottom so the Software product being sold in that market should have UI supporting text from Top to bottom.
• For a software being sold in International market, one of the primary requirements is that it should support the character sets for that particular language e.g. German, Japanese text etc. If the product does not support the local character sets, it cannot be sold in those markets as the consumers will invariably reject the Software whose UI is translated but it does not support data entry in translated language.
• If a product supports multiple languages then one of the possible Internationalization feature is ability to changing the language at a run time.
• One of the important Internationalization requirements is that the core binaries of product (having code for product’s core features) should not change when Software is internationalized in different languages i.e. same code base should be used for a Software in English, German, Japanese languages etc. One of the aims of Internationalization is achieve the same code base across all the languages. If the code base differs as we move from one language to another, then the overall cost of product development and testing becomes multifold.
• And there can be many more such requirements.
And relooking at above 2 broad classifications of requirements, the requirement b) comes under scope of Internationalization i.e. these requirements are covered as a part of Internationalization design and development. So an international Software leverages the features developed in base language (requirement a) above) and in addition includes varios International requirements.
I hope the above examples provides some insights into what Design and Development activities comes under the scope of Internationalization, why is Internationalization important and how is Internationalization different from base product development.

What is Software Localization ?
So, where does Software Localization comes into picture in Software Globalization ? As mentioned earlier- Software Localization is one of the activities of Software Globalization. In simple terms, Localization deals with presentation aspects of International Software. So if I ask what is the basic difference one observes after having a look at German language User Interface as against an English Language user Interface ? The obvious answer is “Language”. So, one of the prime tasks of Software Localization is translation of various User Interface elements in target language. Remember- we are not talking about Localization testing here, its just an plain explanation of term “Software Localization”.

Who does what ?
Software Internationalization is carried out by either the base product developers who are well versed with Internationalization concepts or it is done by the Software Internationalization experts. Internationalization is indeed an experts’ job.
Translation activity in Software Localization is carried out by the language experts preferably by the people who are the native speakers of the language (usually not the people who have learnt the target language as a second language).

Where does Software Internationalization and Software Localization meet ?
In an ideal scenario, Software Internationalization is done when the base product development is being done i.e. Internationalization requirements are built into the Software when the base product is being developed. An important point here is that Internationalization is built into the Software much before it is actually translated. This is an important concept to understand.
The translation work starts only after the base product User Interface is finalized i.e. no more changes are planned to the User Interface. After the User Interface Freeze, the language experts get the English text, they work to translate the same and after the entire translation is done , the translated resources files are included in the product.

Keep watching this space, there’s still a lot more to come on Software Globalization!

Uncovering Myths about Globalization testing-3

Continuing from my previous post , here are a few more myths about Globalization testing uncovered.

Myth 8: If a test case works fine in French language, it will work fine in German language as well

This one is little tricky to explain but it is definitely a myth. Some thoughts around this-
1. Lets consider a case of application being Internationalized for the first time. And assume that the application is going to support multiple languages. There are several factors that need to be kept in mind before defining the testing scope-
a. Check with the developer if there are any changes in application binaries between the languages. If the developer confirms the binaries are the same across all the languages, then get the information about what changes have been done to the product from the Internationalization perspective across all the languages. Also, consider the changes that have been done to the product while building the product or creating the executables. If the product is using the same binaries across all the languages AND there are no changes to the product from the Internationalization perspective AND there are no changes done to build the product AND there are no other changes in the application between languages, then one may confidently say that "If a test case works fine in one language, it will work fine in other language as well. "
In practical scenario, the answer to different if’s in previous sentence are usually not known or is not known to an extent to help you make a right decision. In such a case, to assume that a test case will behave the same way across all the languages may turn out to me quite risky.
b. Continuing with the previous point, another important point is the skill of a developer performing the Internationalization changes to the product. Designing and developing a product from I18N perspective is a specialized skill. More often you will see that the developer who does core application development may not be fully well versed with I18N concepts. If this is the case, as a tester one should better take special care when deciding to omit any test case.
c. If the application is Internationalized for the first time, then the testing should be as thorough as possible as chances for mistakes are high.
2. On the other hand, for the applications that have been through multiple Internationalization releases i.e. already support multiple languages are generally going to be more stable and the variations of test results across the languages would majorly depend upon the changes that has gone into the Software between previous releases and the current one.
3. In order to perform the Risk based testing across the different languages that are supported, one thought-line that is usually applied is that all the Single byte languages such as French, Spanish, German usually tend to behave the same way and the testing can be equally distributed across all these languages.
A special care must be taken to handle the testing of multi-byte languages such as Japanese, Simplified Chinese, Traditional Chinese etc. majorly because of the different character-sets that these languages deal with.

Myth 9: If the Foreign text input in application text fields work fine by using the Soft keys, then it means the data input through respective Foreign language key board would also work fine.

Soft keys are the "Soft" key boards layout in different languages that are provided by Windows Operating System. It can be accessed from the following locations-
- Start Menu/Programs/Accessories/Accessibility/On Screen Keyboards
- Start Menu/Programs/Accessories/System tools/Character Maps

Soft keys basically helps one enter the Foreign text without the need of an external keyboard. For majority of the testing with Foreign text, the use of Soft keys should suffice but there are a few situations that i can think of which requires one to use actual hardware-
- For some languages there are a multiple types of Keyboards (with different makes and models) available in the market. The customers of respective locales can use any of those keyboards. In such a scenarios, it is worthwhile checking at the earlier phases on what models of Keyboards are supported by the application under test and use the same for testing purposes.
- In my testing experience with Internationalized applications, i have not come across a situation where i would have found a bug in which a test scenario worked fine on Soft keyboard but not on physical keyboard but reading about other's experience here's what i found after reading the book- "Galileo Computing- Software Testing and Internationalization"
As the book states- I have seen a program in the past where foreign data was able to be entered correctly using an English keyboard on Portuguese system, so the product was shipped. However, when the program was installed by people in Brazil, who were using a Portuguese keyboard, they were not able to enter the C Celidda character(ҁ).

Though i dont know the exact reason for the above experience mentioned in the book, but this experience is a good enough indicator to not treat the tests related to entering foreign text lightly and to use the physical keyboard for different languages for testing International versions of the Software.
Always, remember- do not take chances with features related to handling the foreign text within the program. Always test it thoroughly.

Myth 10: Globalization testing doesn't require the same test setup as is required to do the Base language testing. Globalization testing can be done with a minimum test setup.

This myth came up as a result of one of the discussions i was having with Development manager of one group. This is a myth because Globalization testing too can be as setup intensive as the base language testing can be.
Remember- one of the basic purposes of Globalization testing is to ensure that the International version of the application on the respective language test setup works the same as English language version would work on English test setup. By test setup here, i mean the Operating System, Third party products, any specific hardware etc.
One cannot possibly carry out all the necessary tests if the test setup of Internationalized applications is not same as the base language test setup.
