Second call of the `elementIdElements()` returns the NightwatchAPI object instead of the expected result #4273

Open MurzNN opened 6 days ago

MurzNN commented 6 days ago

Description of the bug/issue

When I call the this.api.elementIdElements() in a custom command, called from the sync function, on the second call it returns the NightwatchAPI object instead of the actual result.

So, the first call of result = this.api.elementIdElements() returns the array of elements, but when doing the same call a second time - it suddenly returns the NigthwatchAPI object instead!

If I do the same from the async function - all work well.

See the test code below on how to reproduce.

Steps to reproduce

  1. Create a custom Nigthwatch command that calls the function this.api.elementIdElements() multiple times.
  2. Call this command from a Nightwatch test from an async function - all will work well.
  3. Call this command from a Nightwatch test from a sync function - the second call will return the NigthwatchAPI object instead of the expected result.

Sample test

// A test file to call the custom command: Nightwatch/Tests/test1.js

module.exports = {
  'Test thFindNested in async mode': async (browser) => {
    await browser.url('http://google.com');
    const result = await browser.thFindNested();
    console.log('result', result);
  },

  'Test thFindNested in sync mode': (browser) => {
    browser
      .url('http://google.com')
      .thFindNested(result => {
        console.log('result', result);
      });
  },
}

// A custom command file: Nightwatch/Commands/thFindNested.js

module.exports = class thFindNested {
  async command(callback) {
    const el1 = await this.api.findElement('body');
    console.log('el1', el1);
    const el1Id = el1.getId();
    console.log('el1Id', el1Id);

    const els2 = await this.api.elementIdElements(el1Id, 'css selector', 'div')
    console.log('els2', els2);
    const el2 = els2[0];
    console.log('el2', el2);
    // The function elementIdElements() returns elements without the getId() method.
    const el2Id = Object.values(el2)[0];
    console.log('el2Id', el2Id);

    const els3 = await this.api.elementIdElements(el2Id, 'css selector', 'div')
    console.log('els3', els3);
    const el3 = els3[0];
    console.log('el3', el3);
    // The function elementIdElements() returns elements without the getId() method.
    const el3Id = Object.values(el3)[0];
    console.log('el3Id', el3Id);

    if (typeof callback === 'function') {
      const self = this;
      const result = {
        status: 0,
        value: el3Id
      }
      callback.call(self, result);
    }

  }

};

The interesting thing is that if I do this inside the Nightwath test directly - it works well! The issue appears only if I put it into the Nightwatch command and call it from the sync function.

Example of the working tests without the custom function:

module.exports = {
  'Test thFindNested in async mode': async (browser) => {
    await browser.url('http://google.com');
    const el1 = await browser.findElement('body');
    const el1Id = el1.getId();
    console.log('el1Id', el1Id);

    const els2 = await browser.elementIdElements(el1Id, 'css selector', 'div')
    const el2 = els2[0];
    console.log('el2', el2);
    const el2Id = Object.values(el2)[0];
    console.log('el2Id', el2Id);

    const els3 = await browser.elementIdElements(el2Id, 'css selector', 'div')
    console.log('els3', els3);
    const el3 = els3[0];
    console.log('el3', el3);
    const el3Id = Object.values(el3)[0];
    console.log('el3Id', el3Id);
  },

  'Test thFindNested in sync mode': (browser) => {
    browser
      .url('http://google.com')
      .findElement('body', (result) => {
        const el1 = result.value;
        const el1Id = el1.getId();
        console.log('el1Id', el1Id);

        browser.elementIdElements(el1Id, 'css selector', 'div', function (result) {
          const els2 = result.value;
          const el2 = els2[0];
          console.log('el2', el2);
          const el2Id = Object.values(el2)[0];
          console.log('el2Id', el2Id);

          browser.elementIdElements(el2Id, 'css selector', 'div', function (result) {
            const els3 = result.value;
            console.log('els3', els3);
            const el3 = els3[0];
            console.log('el3', el3);
            const el3Id = Object.values(el3)[0];
            console.log('el3Id', el3Id);
          });
        });
      })
      .end();
  },
};
