Now we are going to create some unit automated tests.</p>\n<p>Before to start coding, let's understand how the unit tests works.</p>\nhttps://cdn.steemitimages.com/DQmSdG6gBRNrvhzQ12rRfAEGD9tRpVJnzquMDZMg7WgQNQp/maxresdefault.jpg\n<p>The goal of unit testing is to isolate each part of the program and show that the individual parts are correct.</p>\n<p>Usually, the developer is responsible to write unit tests. To write a good test a devoloper should follow some good practices: First, try to test alll operators of an object. Second, set and get values for all attributes of an object and finally, put your object in all possible states.</p>\n<p><strong>A test is divided in three steps</strong></p>\n<ol>\n<li><strong>Scenario</strong></li>\n<li><strong>Action</strong></li>\n<li><strong>Validation</strong></li>\n</ol>\n<p>Scenario is resposible for <strong>create everything</strong> that will <strong>necessary</strong> to run a function.</p>\n<p>Action, at this part you have to literally <strong>run your function</strong> using those objects started on the scenario step.</p>\n<p>The last step is the <strong>validation</strong>, at this one, you have to check if the <strong>result</strong> of the function, called on action, is <strong>exactly what you expect.</strong></p>\n<p><strong>That's it, let's start our code.</strong></p>\n<p>First, let's create a simple business role for our List Domain.</p>\n<p>**The List name cannot be empty.</p>\n<p>So, when you call the save method you have to check it out.</p>\n<pre><code>\n\t@Transactional\n\t@RequestMapping(value = \"savelist\", method = RequestMethod.POST)\n\tpublic String save(@RequestParam(\"name\") String name, Model model) {\n\n\t\t// Validate Name Error\n\t\tif (name == null || name.isEmpty()) {\n\t\t\tthrow new RuntimeException(\"List name cannot be empty or null\");\n\t\t}\n\n\t\tListDomain list = new ListDomain(name);\n\n\t\trepoList.save(list);\n\n\t\treturn this.lists(model);\n\t}\n</code></pre>\n<p>Now, le'ts create a simple class of test</p>\n<pre><code>\nimport static org.junit.Assert.assertTrue;\n\nimport org.junit.Before;\nimport org.junit.Rule;\nimport org.junit.Test;\nimport org.junit.rules.ExpectedException;\nimport org.mockito.Mock;\nimport org.mockito.MockitoAnnotations;\nimport org.springframework.ui.Model;\n\nimport br.com.namom.todolist.controller.ListController;\nimport br.com.namom.todolist.persistence.ListRepository;\n\npublic class ListControllerTest {\n\n\t@Mock\n\tListRepository repoList;\n\t\n\tprivate ListController listContr;\n\t\n\t@Mock\n\tModel model;\n\t\n\t@Rule\n\tpublic ExpectedException thrown = ExpectedException.none();\n\n\t@Before\n\tpublic void setUp() {\n\t\tMockitoAnnotations.initMocks(this);\n\t\tthis.listContr = new ListController(repoList);\n\t}\n\n\t@Test\n\tpublic void shouldSaveANewList() {\n\t\t// scenario\n\t\tString listName = \"My New List\";\n\n\t\t// action\n\t\tString page = listContr.save(listName, model);\n\n\t\t// validation\n\t\tassertTrue(page.equalsIgnoreCase(\"mylists\"));\n\t}\n\t\n\t@Test\n\tpublic void shouldNotSaveANewListWhenEmptyName() {\n\t\t// scenario\n\t\tString listName = \"\";\n\t\tthrown.expect(Exception.class);\n\t\tthrown.expectMessage(\"List name cannot be empty or null\");\n\n\t\t// action\n\t\tlistContr.save(listName, model);\n\n\t}\n\t\n\t@Test\n\tpublic void shouldNotSaveANewListWhenNameIsNull() {\n\t\t// scenario\n\t\tString listName = null;\n\t\tthrown.expect(Exception.class);\n\t\tthrown.expectMessage(\"List name cannot be empty or null\");\n\n\t\t// action\n\t\tlistContr.save(listName, model);\n\n\t}\n</code></pre>\n<p>One can note that you have to mock some objects before to start your tests. This is necessary because you will not start your application and those objects have to be create.</p>\n<p>Another important highlight is the name of the test functions, it should always be as much explained as you need.</p>\n<p>Ex:&nbsp; <em>shouldNotSaveANewListWhenNameIsNull</em></p>\n<p>That's it.</p>\n<p>Just run the application and you will see it working.</p>\n<p>Checkout the full code on my&nbsp;<a title=\"This link will take you away from steemit.com\" href=\"https://github.com/namomalencar/simpletodolist\" rel=\"nofollow noopener\">github</a>.</p>\n</html>",

Our list is gonna have: Id, name and date.</p>\n<pre><code>import java.io.Serializable;<br>\nimport java.util.Date;<br>\n<br>\nimport javax.persistence.Entity;<br>\nimport javax.persistence.GeneratedValue;<br>\nimport javax.persistence.GenerationType;<br>\nimport javax.persistence.Id;<br>\n<br>\nimport lombok.Data;<br>\n<br>\n@Entity<br>\n@Data<br>\npublic class ListDomain implements Serializable {<br>\n\tprivate static final long serialVersionUID = 1L;<br>\n<br>\n\t@Id<br>\n\t@GeneratedValue(strategy = GenerationType.IDENTITY)<br>\n\tprivate Long id;<br>\n<br>\n\tprivate String name;<br>\n\t<br>\n\tprivate Date date;<br>\n<br>\n\tpublic ListDomain(String name) {<br>\n\t\tthis.name = name;<br>\n\t\tthis.date = new Date();<br>\n\t}<br>\n\t<br>\n\tpublic ListDomain() {<br>\n\t}<br>\n<br>\n}</code></pre>\n<p><strong>Second,&nbsp;</strong>lets create an interface to be able to connect our list to the data base.</p>\n<pre><code>import org.springframework.data.jpa.repository.JpaRepository;<br>\n<br>\nimport br.com.namom.todolist.domain.ListDomain;<br>\n<br>\npublic interface ListRepository extends JpaRepository&lt;ListDomain, Long&gt; {<br>\n<br>\n}<br>\n</code></pre>\n<p><strong>Third,</strong> before to create our controller, lets create our view part. We have created a simple index page that you can find <a href=\"https://github.com/namomalencar/simpletodolist/blob/master/src/main/resources/templates/index.html\">here</a>. Then, we have to create another <a href=\"https://github.com/namomalencar/simpletodolist/blob/master/src/main/resources/templates/lists.html\">page</a> to handle our list, i.e, a page where we can create and list them.</p>\n<p><strong>Fouth,</strong>&nbsp;now lets create our controller. It is resposible to manage our routes, list and save our objects.</p>\n<pre><code>import javax.transaction.Transactional;<br>\n<br>\nimport org.springframework.beans.factory.annotation.Autowired;<br>\nimport org.springframework.stereotype.Controller;<br>\nimport org.springframework.ui.Model;<br>\nimport org.springframework.web.bind.annotation.RequestMapping;<br>\nimport org.springframework.web.bind.annotation.RequestMethod;<br>\nimport org.springframework.web.bind.annotation.RequestParam;<br>\n<br>\nimport br.com.namom.todolist.domain.ListDomain;<br>\nimport br.com.namom.todolist.persistence.ListRepository;<br>\n<br>\n@Controller<br>\npublic class ListController {<br>\n<br>\n\t@Autowired<br>\n\tprivate ListRepository repoList;<br>\n\t<br>\n\t@Transactional<br>\n\t@RequestMapping(\"mylists\")<br>\n\tpublic String lists(Model model) {<br>\n\t\tIterable lists = repoList.findAll();<br>\n\t\tmodel.addAttribute(\"lists\", lists);<br>\n\t\treturn \"lists\";<br>\n\t}<br>\n\t<br>\n\t@RequestMapping(\"\")<br>\n\tpublic String index(Model model) {<br>\n\t\treturn \"index\";<br>\n\t}<br>\n<br>\n\t@Transactional<br>\n\t@RequestMapping(value = \"savelist\", method = RequestMethod.POST)<br>\n\tpublic String save(@RequestParam(\"name\") String name, Model model) {<br>\n\t\tListDomain list = new ListDomain(name);<br>\n\t\trepoList.save(list);<br>\n\t\treturn this.lists(model);<br>\n\t}<br>\n<br>\n}<br>\n</code></pre>\n<p>That's it.</p>\n<p>Just run the application and you will see it working.</p>\n<p>Checkout the full code on my&nbsp;<a href=\"https://github.com/namomalencar/simpletodolist/tree/f93bcb037b9766fb86b16acd5735488e49015643\" rel=\"nofollow noopener\" title=\"This link will take you away from steemit.com\">github</a>.</p>\n<p></p>\nhttps://cdn.steemitimages.com/DQmNhdLHV1n5F4MeMEqXGbP9gJBPrsHkzmtPsZGdZbnZd4B/6.PNG\n</html>",

Usually, it is necessary to make a lot of configurations before start coding.\n\nSpring Boot brought the ideia of making configuration as simple as possible. It the next article we going to build a simple to do list with Spring Boot.\n\n* Spring Boot (Introduction) - Part 1\n\n* Spring Boot (Building a web application - Running) - Part 2\n\n* Spring Boot (Building a web application - JPA integration) - Part 3\n\n* Spring Boot (Increasing your productivity with Spring devtools) - Part 4\n\n* Spring Boot (Building a standalone library) - Part 5\n\n* Spring Boot (Generating a FATJAR) - Part 6\n\n* Spring Boot (Publishing at AWS) - Part 7\n\n\nSpring Boot is a Spring project that indends to make the configuration process as simple as possible. It configures by it self with just a few steps, you only need to set wich modules you desire to use at your project and the Spring Boot will reconize and configure it for you.\n\nYou choose modules and put them at pom.xml file. These modules are dependencies that group other dependencies, there is a dependency called starter that group all needed dependencies to start a project.\n\nAlthough Spring Boot configures every thing, you are able to make your own configuration. The mainly benefit of Spring Boot is that it let us free to concerned only about the business rules of our application.",

Usually, it is necessary to make a lot of configurations before start coding.\n\nSpring Boot brought the ideia of making configuration as simple as possible. It the next article we going to build a simple to do list with Spring Boot.\n\n* Spring Boot (Introduction) - Part 1\n\n* Spring Boot (Building a web application - Running) - Part 2\n\n* Spring Boot (Building a web application - JPA integration) - Part 3\n\n* Spring Boot (Increasing your productivity with Spring devtools) - Part 4\n\n* Spring Boot (Building a standalone library) - Part 5\n\n* Spring Boot (Genarating a FATJAR) - Part 6\n\n* Spring Boot (Publishing at AWS) - Part 7\n\n\nSpring Boot is a Spring project that indends to make the configuration process as simple as possible. It configures by it self with just a few steps, you only need to set wich modules you desire to use at your project and the Spring Boot will reconize and configure it for you.\n\nYou choose modules and put them at pom.xml file. These modules are dependencies that group other dependencies, there is a dependency called starter that group all needed dependencies to start a project.\n\nAlthough Spring Boot configures every thing, you are able to make your own configuration. From my poing of view, the biggest gain of Spring Boot is \n\nThe mainly benefit of Spring Boot is that it let us free to concerned only about the business rules of our application.\n\n![download.png](https://cdn.steemitimages.com/DQmPBXsmxuFT6ZBWn3YMmDnpPFd5ahT5TTyJUoUTUQyPnMK/download.png)",

We can just add the firstString with the secondString;\n\nSample 1:\nString firstString = “Fisrt Name”;\nString secondString = “Last Name”;\nString finalString = firstString + secondString;\nSystem.out.println(finalString);\n\nBut, some times it is necessary to concat a large amount of data, using a looping or something else;\n\nSample 2:\nString s1 = “Numbers separated by comma: “;\nString s2 = “”;\nString s3 = “”;\n for (int i = 0; i <= size; i++) {\ns2 = s2 + i + “, “;\n}\ns3 = s1 + s2;\n\nWhen we deal with a large amount of data we need to take into consideration the performance of the algorithm;\n\nOn our sample 1 and sample 2 the JVM(java virtual machine) is going to create one new object for each concatenation and this may turn into a real problem when we have to concat a large amount of data.\n\nOk, this is a problem… But how can we do that without create a new object for each concatenation?\n\nAnswer:\nThere is an object to deal with this type of problem, it is called “StringBuilder” and we can use it’s native method called “append“, this method receaves as parameter the new string with you intend to concat.\n\nSample 3:\nString s1 = “Numbers separated by comman: “;\nStringBuilder s2 = new StringBuilder();\nString s3 = “”;\nfor (int i = 0; i <= size; i++) {\ns2.append(i).append(“, “);\n}\ns3 = s1 + s2;\n\nOur focus is on performance, so, let’s see some results:\n400 numbers:\nAppending strings: 1ms\nAdding strings: 1ms\n\n4000 numbers:\nAppending strings: 2ms\nAdding strings: 45ms\n\n40000 numbers:\nAppending strings: 7ms\nAdding strings: 4342ms\n\nAnalysing these number we may see that:\nWith 400 numbers both result need the same amount of time to execute;\nWith 4000 numbers the use of the append method is 22 times faster than adding strings;\nWith 40000 numbers the use of the append method is 620 times faster than adding strings;\n\n[Try it for your self ](https://github.com/fortDev/Tips/blob/master/src/string/StringConcat.java)– get the code on the github repository.",
