目录 一.学习D3我必须要学习好SVG矢量图码? 二.如何理解D3给Dom节点绑定数据时的Update.Enter和Exit模式 三.D3绑定数据时用datum与data有什么不一样? 四.SVG图中用attr来设置属性和用style来设置样式时,用style来设置样式的权重会更高 五.D3使用链式写法时,写完transition动画后不能链着继续写append添加元素操作 六.如何给path设置缓动? 七.D3普通的缓动动画 八.给节点添加title,鼠标mouseover显示普通提示文本效果…
What is Table-Driven and Data-Driven Programming? Data/Table-Driven programming is the technique of factoring repetitious programming constructs into data and a transformation pattern. This new data is often referred to by purists as meta-data when u…
Data Driven Testing Peter Niederwieser, The Spock Framework TeamVersion 1.1 Oftentimes, it is useful to exercise the same test code multiple times, with varying inputs and expected results. Spock’s data driven testing support makes this a first class…
关于ddt模块的一些心得,主要是看官网的例子,加上一点自己的理解,官网地址:http://ddt.readthedocs.io/en/latest/example.html ddt(data driven tests)可以让你给一个测试用例传入不同的参数,每个运行一遍,就像是运行了多个测试用例一样. ddt模块包含了一个类的装饰器ddt和两个方法的装饰器: data:包含多个你想要传给测试用例的参数: file_data:会从json或yaml中加载数据: 通常data中包含的每一个值都会作为一…
What is Data Driven Testing? Data-driven is a test automation framework which stores test data in a table or spread spreadsheet format. This allows automation engineers to have a single test script which can execute tests for all the test data in the…

Mapping abstract values to visual representations is what data visualization is all about, and that’s exactly what D3 scales do. Turning a test score into a column height, or a percentage into an opacity requires translating from one set of possible…
