How to resolve error : [wdi5] bridge was not initialized correctly

[nair-sumesh]

Describe the bug Receiving below error several times at the beginning of the test code execution. My test cases passed successfully though. Could this message be resolved or suppressed.

Code

      const elem = await $('#meAreaHeaderButton')
      await elem.waitForDisplayed({ timeout: 3000 });

      const _ui5Service = require('wdio-ui5-service').default
      const wdioUI5Service = new _ui5Service()
      wdioUI5Service.injectUI5()

After this statement the error is raised several times in a row, before the actual actions/assertions are executed.

Logs/Console Output

if you're late-injecting wdi5, with the new async notation, you need to await the injection:

await wdioUI5Service.injectUI5()

Thanks @vobu for the suggestion. The occurrence of the error have now reduced to one. The error is still raised as soon as the test starts.

[vobu]

right on, just for reference: we're having a test for this as well at https://github.com/js-soft/wdi5/blob/develop/wdio-ui5-service/test/ui5-late.test.js i'm taking the liberty to close this

@nair-sumesh I met the same issue, and finally I found I missed the skipInjectUI5OnStart: true config. Example: https://github.com/js-soft/wdi5/blob/develop/wdio-ui5-service/test/wdio-ui5-late.conf.js#L99

[nair-sumesh]

@cwang1221 @vobu In my conf file, I have set

skipInjectUI5OnStart: true   
url: 'index.html'

and

baseUrl,

Later in my spec, I call

await browser.url(sBaseUrl); // sBaseUrl contains the entire URL path to the SAP system

const _ui5Service = require('wdio-ui5-service').default
const wdioUI5Service = new _ui5Service()
await wdioUI5Service.injectUI5()

Observations

• The Chrome loads with index.html (an empty page) ✔
• Then the web page navigates to the base url and user login page is displayed ✔
• Then suddenly the page jumps back to index.html ❌

@vobu Your help is appreciated.

@nair-sumesh do you have wdi5: { url: "index.html" ... }

in your config?

@nair-sumesh do you have wdi5: { url: "index.html" ... }

in your config?

Yes.

  wdi5: {
    screenshotPath: path.join('wdio-ui5-service', 'test', 'report', 'screenshots'),
    logLevel: 'verbose', // error | verbose | silent
    platform: 'browser', // electron, browser, android, ios
    url: 'index.html',
    deviceType: 'web',
    waitForUI5Timeout: 15000,
    skipInjectUI5OnStart: true  
  },

[dominikfeininger]

The flow with skipInjectUI5OnStart: true works like:

• open baseUrl // non UI5 page // done by wdio
• nav to some other page with UI5
• call wdioUI5Service.injectUI5()
• wdi5 uses the url property from config to start

So my guess would be to set the url property to empty string "" in case you don't need it.

Thanks @dominikfeininger . This worked.
