pytest学习笔记

pytest 优于其他测试框架的地方： 1、简单的测试可以简单的写 2、复杂的测试也可以简单的写 3、测试的可读性强 4、易于上手 5、断言失败仅使用原生assert关键字，而不是self.assertEqual()或者self.assertLessThan() 6、pytest可以运行有unitest和nose编写的测试用例 pytest不依赖python的版本，python2和3都能安装最新版的pytest Tasks项目： tasks程序通过CLI交互，底层编码通过调用API实现 很久没有更新博客园，比较好听点的原因是由于项目比较忙，没有时间整理写脚本过程中的问题。实际上是由本人的“懒”，不想写。不写不记录慢慢的就导致了懒癌的形成，久而久之某些知识回了之后就忘记了，好了 废话不多说 记录下最近写代码过程中的一些问题 1、写接口脚本时候，为了实现活动榜单数据制造，需要写一个登录方法 从json返回值中取出token、uid（uid 用来造主播榜单 给不同的主播送礼，token 不同用户给同一个主播送礼，造用户排行榜的榜单）。礼用config文件存储，将多个token从接口中读出存放在list，然后写入config.txt文件中，用来后面送礼 接口读取数据。但是发下config只能存入字符串str，于是后面想一个个的读取就失败了。 如果使用如下方法直接转换成list 不能实现

How to write boolean value as String in a json array?

由 为君一笑 提交于 2021-02-16 06:26:07
问题 JsonGenerator generator = new JsonFactory().createJsonGenerator(new JSONWriter(response)); generator.configure(JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS, true); I used JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS to write numbers as string in json. But, I couldn't find similar feature to write boolean value as string. 回答1: I couldn't find similar feature for boolean, also. So, I propose to write new serializer and deserializer for boolean fields. See my example: public class

微信小程序与java后台交互

java后台使用的ssm框架，小程序连接的本地接口。跟正常的web访问没什么区别，也是后台获取url，返回json数据；只是小程序前台请求的url要带上http://localhost:8080 1. 项目结构 2. 配置文件： Jackson相关包下载 除去里面的js文件 3. test.js和test.wxml (1) test.js bindtest:function(){ wx.request({ url: ' http://ip:8080/WxProgram/buttonTest2 ' , data:{ username: 'admin' , password: 'admin' }, method: 'GET' , header:{ 'content-type':'application/json' }, success:function(res){ console.log(res.data); }, fail:function(res){ console.log( "--------fail--------" ); } }) } (2) test.wxml <view>{{name}}</view> <view> <button bindtap='bindtest'>test</button> </view> 4.

How to read JSON in list of generic

由 会有一股神秘感。 提交于 2021-02-11 17:51:26
问题 I have a helper class calling a REST web service. This helper class receives the information from the web service within a class defined as a generic "R". I can easily use GSON to read my JSON in a POJO, but I can't figure out how to give it a List and read it properly. So far I have tried to extract the type of R in a variable and pass it to the List without success. I have tried using Jackson with its TypeFactory, also without success, it won't take R as its parameter. What I want to do is

Why ObjectNode adds backslash in in Json String

Remove empty JSON objects from an array in Jackson serialization

由 二次信任 提交于 2021-02-11 07:53:31
问题 I have a List in a Java Pojo class. That list contains some MyChildPojo objects which are not null but can have properties with null values. Example: MyChildPojo obj1 = new MyChildPojo(); MyChildPojo obj2 = new MyChildPojo(); I have added @JsonInclude(JsonInclude.Include.NON_EMPTY) on my MyChildPojo class so null properties will not be added while serializing the object. Now my final serialized output for the List object is: [ {}, {} ] I want to remove the complete List object in this case. I

Need MixIn Resolution for non-static Inner Class using ObjectMapper - Java 6

由 廉价感情. 提交于 2021-02-11 06:44:54
问题 I'm facing an issue while using ObjectMapper for non-static inner class. I need to create MixIn to make it work but could not reach to the solution. Below is my class(which I can't change) and the MixIn, I tried. Help needed to create such MixIn. ============================ Base Class public class NestedClass implements Serializable{ private static final long serialVersionUID = -4509619645418618657L; private NestedInnerClass innerClass; public NestedClass() { innerClass = null; setInnerClass

Dynamic root element with Jackson

由 淺唱寂寞╮ 提交于 2021-02-11 06:44:13
问题 I'm currently working on a project that deals with elements that (for legacy reasons) must have a tag name that represents their type. Basically I have this: @JsonRootName("node") class NodeDocument { private String type; } Which outputs something like: <node type="someType"></node> But what's expected would be: <someType></someType> @JsonRootName doesn't seem to be usable on a method or attribute. Even though there is SerializationConfig.withRooName() or custom serializers, I can't seem to
