Junit - Test fails on French or German string assertion

In my previous post about building a regex to check a text without special characters but allow German and French . I met a problem that the unit test works fine on my machine using Eclipse, but it was fail when running on Jenkins' build job. Here is my test: @Test public void shouldAllowFrenchAndGermanCharacters(){ String source = "ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ"; assertFalse(SpecialCharactersUtils.isExistSpecialCharater(source)); } Production code: public static boolean isExistNotAllowedCharacters(String source){ Pattern regex = Pattern.compile("^[a-zA-Z_0-9_ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ]*$"); Matcher matcher = regex.matcher(source); return !matcher.matches(); } The result likes the following: Failed tests: SpecialCharactersUtilsTest.shouldAllowFrenchAndGermanCharacters:32 null A guy from stackoverflow.com says: "This is probably due to the default encoding used for your Java source files. The ö in the string literal in the J...

Git Feature Branch Workflow

Motivator It's important for a team to have an agreement on how the changes of source code should be applied. According to projects and teams size, we will define a workflow or select one from recommended workflows ; the "Feature Branch Workflow" is a candidate. What is it? - One branch "master" for main codebase - Several separated branches for features development Why should we care? - Be super simple and allow each developer works on a particular feature. - A stable codebase (master) benefits for continuous integration (CI) environment - Leverage "Pull request" for Code review How it works? A lifecyle of a feature branch (usually created by a story) 1. Creator creates a new branch from a story. For example: "ABC-1-setup-projects" 2. Creator checkouts the created branch and works on the branch (commits, pushes) 3. Creator has done the feature, he uses "pull request" to merge his branch into branch "master...

Managing JAR files with Apache Maven

Apache Maven (Maven) is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information. Why Maven? Let’s learn about the Maven’s history here https://maven.apache.org/background/history-of-maven.html to understand why Maven is created. There are a lot of useful things that we should use Maven. In my opinion, the most important thing is that Maven solves the problems with managing jar files. It centralizes these files in one place and it is easy to use by declaring dependencies in a xml file (pom.xml). Using Maven to manage JAR files Firstly, I would like to give you an example about using some JAR files without Maven. In my project, I need some JAR files such as SNMP4J.jar, jta26.jar, jgraphx.jar, etc… so I had to search them on the Internet with visiting a lot of websites, download and add these files into my proje...

My must-have apps for daily work

There is no doubt that cool apps can help us be more productive and enjoyable at work. For the time being, I really love the following apps which are used by me almost every day. 1. A personal Kanban In fact, a personal kanban is the most useful app for me. Why does it matter? It is not just a to-do list, but it keeps me motivated every day because it helps me be able to know what my "big picture" is. I usually set up my plans together with a path to reach them. KanbanFlow is my preferred tool. KanbanFlow 2. A terminal Needless to say, a terminal is a must-have app for every developer, especially the ones use macOS/Linux. Due to its importance, I love to decorate and enhance it to be super exciting with various tools such as iTerm , oh-my- zsh , and thefuck . ;) iTerm + oh-my-zsh 3. A documentation "ecosystem" As a developer, I can not remember all things that I have experimented a day. Moreover, a document is really useful for sharing an...

The HelloWorld example of JSF 2.2 with Myfaces

I just did by myself create a very simple app "HelloWorld" of JSF 2.2 with a concrete implementation Myfaces that we can use it later on for our further JSF trying out. I attached the source code link at the end part. Just follow these steps below: 1. Create a Maven project in Eclipse (Kepler) with a simple Java web application archetype "maven-archetype-webapp". Maven should be the best choice for managing the dependencies , so far. JSF is a web framework that is the reason why I chose the mentioned archetype for my example. 2. Import dependencies for JSF implementation - Myfaces (v2.2.10) into file pom.xml . The following code that is easy to find from http://mvnrepository.com/ with key words "myfaces". <dependency> <groupId>org.apache.myfaces.core</groupId> <artifactId>myfaces-api</artifactId> <version>2.2.10</version> </dependency> <dependency> <groupId>org.apache.myfaces.core<...
