No difficulties, no discovery

Bill Gate had said that “I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it.” In my opinion, that remark is so true in some cases.

My team has tried to apply integration tests for our projects. Firstly, we had meeting to figure out what problems we met. Then, we decided to create a new project that is similiar to the current one and we called it a prototype project. Yeah, I and some members were reponsile for it.

I spent a lot of time and took a lot of efforts for coppying the current project because its domain logic was really complicated. What a boring task! I smelt a rat and felt too lazy. At that time, I thought that I need a change. I discussed with others: "Why don't we just create a branch of curent project and work on it?". We didn't need spending time for coppying anymore. Just forked it and modified on it. Therefore, it was really a good solution.

Leave your comments about that. ;)

[Snippet] CSS - Child element overlap parent

I searched from somewhere and found that a lot of people says a basic concept for implementing this feature looks like below: HTML code: <div id="parent"> <div id="child"> </div> </div> And, CSS: #parent{ position: relative; overflow:hidden; } #child{ position: absolute; top: -1; right: -1px; } However, I had a lot of grand-parents in my case and the above code didn't work. Therefore, I needed an alternative. I presumed that my app uses Boostrap and AngularJs, maybe some CSS from them affects mine. I didn't know exactly the problem, but I believed when all CSS is loaded into my browser, I could completely handle it. www.tom-collinson.com I tried to create an example to investigated this problem by Fiddle . Accidentally, I just changed: position: parent; to position: static; for one of parents -> the problem is solved. Look at my code: <div class="modal-body dn-placeholder-parent-positi...

Selenium - Use Explicit Waits for checking elements quickly disappear like loading icon

I have a table that is displayed a list of competence groups. When I click on a competence group, it will display a table that contains a lot of criteria belong to the competence group. Each times I click on a competence group, a "loading" icon is displayed while waiting for all criteria is fully displayed. <div id="loading" style="display: none;"> <div></div> <div></div> I tried to write a Selenium test to make sure this behavior is covered. I saw that the loading icon element is always available on DOM tree because I just used Jquery to handle its displaying. Beside that, the loading icon is appeared dynamically and quickly disappear afterwards. It is hard to checking the visibility on GUI of loading icon. By normal way that I frequently used, the code looks like: public boolean isLoadingIconDisplayed() { List<WebElement> loadingIcons = driver.findElements(By.id("loading")); if(!loadingIcons.isE...

How to apply Lean - Kanban for your business

This is the topic of Scrum Breakfast meetup this time, speaker: Ms. Phuong Bui - Technical Project Manager of YOOSE Pte. Ltd. http://www.meetup.com/Scrum-Breakfast-Vietnam-Agile-and-Scrum-Meetup/events/230313727/ Lean comes from Lean manufacturing is a method that focuses on elimination of wastes. In other words, this is a set of principles for archiving the quality, speed and customer alignment. The first time I knew about the term "Lean" is from the book Software Craftsmanship . Sandro recommends if we want to transform our pet projects into a real business, we should get familiar with Lean Startup concepts. In this talk, Ms. Phuong pointed out some major wastes includes information (ex: unclear requirements), processes (ex: waiting), physical environment and people. Knowing what the problems should be the best way to eliminate them. The difference between Single item flow and Batch processing is the second main point; and it is the Lean's idea. Batch pr...

git cherry-pick [commit]

Customer Needs My team already had a go-live app in a customer environment some months ago. We have been developing some new features for our next milestone. The situation is described in the picture below: We used Git for our codebase management. The go-live app running on our customer environment was at version ` v1 `. The latest sprint release was at version ` v7 ` for our developing app. Our customers wanted to have two separated release packages for our current sprint release. We all know that it was easy to ship the package to the developing app. However, the issue was that how we just picked some features needed for the go-live app. We called this package was a hotfix. Git Cherry-Picking Fortunately, we found that Git provided a way to achieve this task. Actually, we had all commits on the branch ` master ` already. We created a new branch called ` hotfix/v1.1 ` and we traced back which commits needed. We used cherry-picking for merging these commits to this branch....

Multiple Inheritance of State and Implementation

Today, I was just curious about why an enum can not extend anything else. I took a look on the Oracle document here , and I found the answer is below: "All enums implicitly extend java.lang.Enum. Because a class can only extend one parent (see Declaring Classes), the Java language does not support multiple inheritance of state (see Multiple Inheritance of State, Implementation, and Type), and therefore an enum cannot extend anything else." I have been learned of it before. But, wait a sec...! Why Java does not support multiple inheritance of state? Since I have worked with other programming languages like C++, I was able to make a class extend some other classes. The short answer is to avoid the issues of multiple inheritance of state . I wonder if other programming languages have these below terms but Java does. Multiple inheritance of state It is the ability to inherit fields from multiple classes. There is a problem and Java avoids it. "For exa...
