You can make your own custom command that uses browser.assert.

module.exports = {
  'Length of text should be greater zero': function(browser) {

    browser
      .url('..')
      .getText('#some-selector', function(result) {
        browser.assert.ok(result.value.length > 0);
      })
      .end();
  }
};
