When running junit-4.12 testcases via ant -d with XML reporting enabled my testsuite is not executed. This is part of build.xml: <target name="compile" depends="prepare"> <!-- kompilieren der Quelldateien --> <javac includeantruntime="false" srcdir="${source.dir}" destdir="${build.dir}"> <classpath> <path refid="classPath"/>
当通过启用XML报告的ant -d运行junit-4.12测试用例时，我的测试套件不会执行。 这是build.xml的一部分： <target name="compile" depends="prepare"> <!-- kompilieren der Quelldateien --> <javac includeantruntime="false" srcdir="${source.dir}" destdir="${build.dir}"> <classpath> <path refid="classPath"/> <pathelemen
I need to write JUnit tests for an old application that's poorly designed and is writing a lot of error messages to standard output. When the getResponse(String request) method behaves correctly it returns a XML response: @BeforeClass public static void setUpClass() throws Exception { Properties queries = loadPropertiesFile("requests.properties"); Properties responses = loadProperti
我需要为一个设计不好的旧应用程序编写JUnit测试，并且会向标准输出写入大量错误消息。 当getResponse(String request)方法行为正确时，它返回一个XML响应： @BeforeClass public static void setUpClass() throws Exception { Properties queries = loadPropertiesFile("requests.properties"); Properties responses = loadPropertiesFile("responses.properties"); instance = new ResponseGenerator(queries, r
I am configuring JUnit in Ant so that unit tests will be run on each build. I would like the output of failing tests to be printed in the Ant console output whenever they are run. I don't need to see any output from succeeding tests. Here is the relevant bit of my build.xml file: <junit> <classpath> <pathelement path="${build}"/> </classpath> &
我在Ant中配置JUnit，以便在每个版本上运行单元测试。 我希望失败的测试输出在运行时在Ant控制台输出中打印。 我不需要看到成功测试的任何输出。 这里是我的build.xml文件的相关位： <junit> <classpath> <pathelement path="${build}"/> </classpath> <formatter type="brief" usefile="false"/> <batchtest> <fileset dir="${src}" includes="my/
Assume we have a trivial Java program that consists of just one class: public class HelloWorld { private static void replacable(int i) { System.out.println("Today is a nice day with a number " + i); } public static void main(String[] args) throws Exception { for(int i = 0; i < 100000; ++i) { replacable(i); Thread.sleep(500); } } After it's co
假设我们有一个简单的Java程序，它只包含一个类： public class HelloWorld { private static void replacable(int i) { System.out.println("Today is a nice day with a number " + i); } public static void main(String[] args) throws Exception { for(int i = 0; i < 100000; ++i) { replacable(i); Thread.sleep(500); } } 编译并运行后，输出结果如下： 今天是一
I wrote an Android application. Now, I want to make the device vibrate when a certain action occurs. How can I do this? Try: import android.os.Vibrator; ... Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); // Vibrate for 500 milliseconds if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { v.vibrate(VibrationEffect.createOneShot(500,
我写了一个Android应用程序。 现在，我想在发生某些操作时使设备振动。 我怎样才能做到这一点？ 尝试： import android.os.Vibrator; ... Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); // Vibrate for 500 milliseconds if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { v.vibrate(VibrationEffect.createOneShot(500,VibrationEffect.DEFAULT_AMPL
I am currently working on a graphs library for Java. As you expect there exists a Vertex class. That class contains an object of type VertexData<T> and that itself can contain anything. (I know this might be redundant and i could just do Vertex<T> but for the purpose of the question it doesn't matter). I made VertexData<T> implement Cloneable and have a public VertexDa
我目前正在研究Java的图形库。 正如你所期望的那样，存在一个Vertex类。 该类包含VertexData<T>类型的对象，并且它本身可以包含任何内容。 （我知道这可能是多余的，我可以做Vertex<T>但为了这个问题的目的不重要）。 我使VertexData<T>实现了Cloneable并且有一个public VertexData<T> clone()方法，通过对调用Object进行序列化和反序列化来返回深层副本，非常像这里描述的 现在的问题是，因为
When I start to commit changes to the VCS, the following commit dialog appears. I checked the option 'Perform code analysis'. If I press commit, the code analysis starts, and when its finished i get the following dialog to view the results of the analysis: If I press the review button I can review the results. I would like to start exactly the same analysis manually. My version of
当我开始提交对VCS的更改时，会显示以下提交对话框。 我检查了“执行代码分析”选项。 如果我按提交，代码分析开始，当它完成时，我得到以下对话框来查看分析结果： 如果我按下查看按钮，我可以查看结果。 我想手动开始完全相同的分析。 我的IntelliJ IDEA版本：14.1.1（建立于2015年3月31日） 在IntelliJ中没有提交就可以运行提交对话框的代码分析？ 分析 - >检查代码（马巴的回答）是正确的。 您可以在项目设置
We are computing something whose runtime is bound by matrix operations. (Some details below if interested.) This experience prompted the following question: Do folk have experience with the performance of Java libraries for matrix math (eg, multiply, inverse, etc.)? For example: JAMA COLT Apache commons math I searched and found nothing. Details of our speed comparison: We are usi
我们正在计算一些运行时受矩阵运算约束的东西。 （如果有兴趣，请参阅下面的一些细节。）这种体验引发了以下问题 民间人士是否具有矩阵数学Java库的性能的经验（例如，乘，反等）？ 例如： JAMA 小马 阿帕奇公用计算器 我搜索，没有发现任何东西 我们的速度比较详情： 我们正在使用英特尔FORTRAN（ifort（IFORT）10.1 20070913）。 我们已经使用Apache commons math 1.2 matrix ops在Java（1.6）中重新实现了它
For my class assignment we need to Write a class called Matrix that contains a private 2-dimensional int array called 'matrix' that can be up to 10 rows by 10 columns maximum. We need to use two constants MAXROWS=10 and MAXCOLS=10 to construct 'matrix.' The Matrix class will also need the following attributes: private int rows; // number of rows to use in matrix private int
对于我的类分配，我们需要编写一个名为Matrix的类，其中包含一个名为'matrix'的私有2维int数组，该数组可以最多10行10列。 我们需要使用两个常量MAXROWS = 10和MAXCOLS = 10来构造“矩阵”。 Matrix类还需要以下属性： private int rows; // number of rows to use in matrix private int cols; // number of cols to use in matrix 行和列将包含小于等于MAXROWS和MAXCOLS的值。 编写一个默认的Matrix类构造函数
