Jenkins⾼级篇之Pipeline技巧篇-4-根据参数传⼊条件控制执⾏
不同stage
这篇我来介绍⼀下之前，很早的时候介绍pipeline语法的时候，有⼀个指令叫when 和expression，当时由于pipeline知识学习太少，不好举例⼦去学习消化。到了这⾥，其实这两个关键字就是⽤来控制stage的执⾏，如果你条件有好⼏个，可以精确控制让哪⼀些stage执⾏，让哪⼀些stage不执⾏。
我这⾥举例⼀个⾃动化测试中的例⼦，例如我写了多个stage，这个pipeline脚本执⾏执⾏冒烟测试，和集成测试。有时候，我们希望快速执⾏冒烟测试，想根据结果看看，不⼀定⼀上来就执⾏集成测试。为了达到这种控制效果，我们就需要使⽤逻辑控制。在pipeline中就使⽤when 和expression两个命令。例如，如果json⽂件中冒烟测试变量为true，我就只执⾏冒烟测试的stage，其他和冒烟测试⽆关的stage我就不去执⾏。如果冒烟测试变量值为fal，也就是默认要跑集成测试（不跑冒烟测试）。为了不搞得这么复杂，我们就分两个类型测试就好。下⾯，我⽤pipeline代码⽅式去实现。
1.json准备
{
"NAME" : "Lucy",
"AGE" : "18",
"PHONE_NUMBER" : "139********",
"ADDRESS" : "Haidian Beijing",
"EMAIL" : "",
"GENDER" : "male",
"SMOKE": true,
"IS_MARRY" : fal
}
我还是在前⾯⽂章的/tmp/anthony/test.json⽂件基础上加了⼀个变量 SMOKE， 默认值是true。
2.pipeline stage groovy⽂件代码
由于我添加了⼀个SMOKE的变量，所以在初始化stage，我们新增⼀⾏代码，初始化SMOKE的变量。
del.*;
pipeline{
agent any
stages{
stage("Hello Pipeline") {
steps {
script {
println "Hello Pipeline!"
println env.JOB_NAME
println env.BUILD_NUMBER
}
}
}
stage("Init paramters in json") {
steps {
script {
println "read josn input file"
json_file = INPUT_JSON? im() : ""
prop = readJSON file : json_file
name = prop.NAME? im() : ""
println "Name:" + name
age = prop.AGE? im() : ""
println "Age:" + age
phone = prop.PHONE_NUMBER? prop.im() : ""
println "Phone:" + phone
println "Phone:" + phone
address = prop.ADDRESS? im() : ""
println "Address:" + address
email = prop.EMAIL? im() : ""
println "Email:" + email
gender = prop.GENDER? im() : ""
println "Gender:" + gender
is_marry = prop.IS_MARRY? prop.IS_MARRY : fal
println "is_marry:" + is_marry
is_smoke = prop.SMOKE? prop.SMOKE : fal
println "is_smoke:" + is_smoke
}
}
}
stage("call a method") {
steps {
script {
println "nd the parameter as map type"
model_call = load env.WORKSPACE + "/vy"
UrInfo(name:name, age:age, phone:phone, address:address, email:email, gender:gender, is_marry:is_marry) }
}
}
stage("check rive up") {
when {
expression {
return (is_smoke == true)
}
}
steps {
script {
println "SMOKE TEST: check rvice startup"
}
}
}
stage("check UI login") {
when {
expression {
return (is_smoke == true)
}
}
steps {
script {
println "SMOKE TEST: check UI login success"
}
}
}
stage("Integrate-ModelA") {
when {
expression {
return (is_smoke == fal)
}
}
steps {
script {
println "Integrate-ModelA"
}
}
}
stage("Integrate-ModelB") {
when {
expression {
return (is_smoke == fal)
}
}
}
steps {
script {
println "Integrate-ModelB"
}
}
}
}
}
3.测试效果
只跑冒烟测试，也就是SMOKE的值在json中是true
