javascript - 无法点击元素

Question

<div class="MuiGrid-root jss48321 MuiGrid-item MuiGrid-grid-xs-12 MuiGrid-grid-sm-3 MuiGrid-grid-md-3 MuiGrid-grid-lg-3 MuiGrid-grid-xl-3">
<h4 class="MuiTypography-root jss48324 MuiTypography-h4">Decks</h4>
<button class="MuiButtonBase-root MuiFab-root jss48323 MuiFab-sizeSmall MuiFab-primary" tabindex="0" type="button" aria-label="add" title="Add">
<span class="MuiFab-label">
<svg class="MuiSvgIcon-root" focusable="false" viewBox="0 0 24 24" aria-hidden="true">
<path d="M19 13h-6v6h-2v-6H5v-2h6V5h2v6h6v2z"></path>
</svg>
</span>
<span class="MuiTouchRipple-root"></span>
</button></div>

由于它是react js应用程序，我补充说

browser.waitForAngularEnabled(false); 

在这里我想点击添加图标(+)
我的测试脚本。
element(by.css('svg[class="MuiSvgIcon-root"]')).click();
输出:失败:使用定位器找不到元素:By(css selector, svg[class="MuiSvgIcon-root"])任何人都可以帮助我解决这个问题。

尝试这个

it('test case', async () => {
  let plusIcon = element(by.css('svg[class="MuiSvgIcon-root"]'))
  await browser.waitForAngularEnabled(false); 
  // your steps prior to click
  await browser.wait(
    ExpectedConditions.presenseOf(plusIcon),
    15000
  );
  await plusIcon.click();
});
