Suppose that we have a list of employees. Everytime, we want to add new employee into this list, the name of the employee will be generated with the following rules: - the name of the new one is set to " [originalname] 1 " - in case the name already exist, " [originalname] 2 " is used, and so on. Here is my code snippet by Javascript: var employees =[ {id: 1, name: 'name'}, {id: 2, name: 'name 1'}, {id: 3, name: 'name 2'}, {id: 5, name: 'name 4'} ]; var commonUtils = { isExistName: function(_name, _collection, _prop) { for(var i = 0; i< _collection.length; i++){ if(_collection[i][_prop].localeCompare(_name)==0){ return true; } } return false; }, generateNewName: function(_name, _collection, _prop){ var i = 1; var searching = true; while (searching) { var newName = _name+ " " + i; if (!this.isExistName(newName, _collection, _pro

Changes is constant, software development as well. Do you know the development of mobile phones, starting from Motorola DynaTAC (1973) to Iphone 6 (2014). How about the software? The new versions are released with new improvements. Software is not always able to automatic repairing. Therefore, software should be changed frequently and we need responding to changes. source:  http://answers.microsoft.com/ In working software today, how about customers' collaboration or requirements? We ignore the fact that many customers don't know what they want . We ignore the fact that when they know what they want, they can't describe it . We ignore the fact the even when they can describe it, they often a proposed solution rather than a real need . We ignore, that a lot of customers g ive us a solution but not the problem . source:  http://accelerateddevelopment.blogspot.com/ And, in working process, earlier founded bugs are cheaper.

"Creates a virtual table whose contents (columns and rows) are defined by a query. Use this statement to create a view of the data in one or more tables in the database. For example, a view can be used for the following purposes: - To focus, simplify, and customize the perception each user has of the database. - As a security mechanism by allowing users to access data through the view, without granting the users permissions to directly access the underlying base tables. - To provide a backward compatible interface to emulate a table whose schema has changed." [1] Beside that, our team used view in order to improve the performance of our web apps when a database has a very complicated relationship between its tables by using ORM Frameworks such as Hibernate. Example code: --create CREATE VIEW placeholders AS SELECT EMPKEY AS empkey, CONNUMB AS connumb, EMPNBR AS empNbr, ACEEMPN AS empFirstName, ACEEMPFN AS empLastName, EMPNAM AS empFullName,

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

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

Special characters such as square brackets ([ ]) can cause an exception " java.util.regex.PatternSyntaxException " or something like this if we don't handle them correctly. I had met this issue. In my case, my customers want our application should allow some characters in German and French even not allow some special characters. The solution is that we limit the allowed characters by showing the validation message on GUI. For an instance, the message looks like the following: "This field can't contain any special characters; only letters, numbers, underscores (_), spaces and single quotes (') are allowed." I used Regular Expression to check it. For entering Germany and French, I actually don't have this type of keyboard, so I referred these sites: * German characters: http://german.typeit.org/ * French characters: http://french.typeit.org/ Here is my code: package vn.nvanhuong.practice; import java.util.regex.Matcher; import java.util
