Cypress.io如何读取Windows环境变量?

来自cypress文档 here :

计算机上的任何环境变量 CYPRESS_ 或 cypress_ 将自动添加并提供给您。

冲突的值将覆盖 cypress.json cypress.env.json

柏树会把树剥掉 添加环境变量时。

从命令行导出cypress env变量:

export CYPRESS_HOST=laura.dev.local

export cypress_api_server=http://localhost:8888/api/v1/

set setx 命令。

在你的测试文件中你可以称之为:

Cypress.env()             // {HOST: "laura.dev.local", api_server: "http://localhost:8888/api/v1"}
Cypress.env("HOST")       // "laura.dev.local"
Cypress.env("api_server") // "http://localhost:8888/api/v1/"

为此,请将cy.exec与echo一起使用。如果在CMD'echo%appdata%'中运行,它将打印路径。我用包装纸把cy.exec包装成

cy.runExec = (js) => {
  cy.log(`--- runnnig node ${js}`);
  cy.exec(js, { failOnNonZeroExit: false }).then((z) => {
    if (z.stderr != undefined) {
      cy.log(`--- stderr`);
      let lines = z.stderr.split("\n");
      for (let n in lines) cy.log(`--- ${n}: ${lines[n]}`);
    }
    if (z.stdout != undefined) {
      cy.log(`--- stdout`);
      let lines = z.stdout.split("\n");
      for (let n in lines) cy.log(`--- ${n}: ${lines[n]}`);
    }      
  });
};

如果你把它叫做 cy.runExec('echo %appdata%') ,它将在cypress输出中打印相同的路径,您可以修改此方法以仅获取标准输出。您还可以使用cy.wrap(…).as(…)保存该值,稍后再获取。

cy.getWinEnv = (s) => {
  cy.exec(`echo %${s}%`, { failOnNonZeroExit: false }).then((z) => {
    let out = z.stdout != undefined ? z.stdout : "undefined";
    cy.wrap(out).as(s);
    //do not: return out;
  });
};

用法:

//read %appdata%
cy.getWinEnv("appdata");

//log %appdata% in cypress
cy.get("@appdata").then((x) => cy.log(`--- ${x}`));

cy.getWinEnvEx = async (s) => {
  var out = "undefined yet";
  await cy.exec(`echo %${s}%`, { failOnNonZeroExit: false }).then((z) => {
    if (z == null) {
      cy.log("--- output is null");
    } else {      
      out = z.stdout != undefined ? z.stdout : "undefined";
      //cy.log(`--- z.stdout ${out}`);
    }
  });
  return out;
};

...

it("list windows variables", async () => {
  let z = await cy.getWinEnvEx("USERPROFILE");
  cy.log(`--- USERPROFILE ${z}`);
});
