用于匹配未通过所有测试场景的单词和数字的正则表达式

Question

使用 .Net Core 3.1，我构建了以下 xUnit 测试来测试我的正则表达式，它应该匹配某些单词，或者那些相同的单词后跟数字：

[Theory]
    [InlineData("Some Demo543 Company", true)]
    [InlineData("Some Company", false)] //why is this one failing
    [InlineData("Some Company123", false)] //why is this one failing
    [InlineData("Some Test123 Company", true)]
    [InlineData("Some Testing123 Company", true)]
    [InlineData("Some Example123 Company", true)]
    [InlineData("Some Demonstration321 Company", true)]
    [InlineData("demo123", true)]
    [InlineData("Testing123", true)]
    [InlineData("Company123", false)]
    [InlineData("Company", false)]
    public void TestRegexSentenceContainsWholeWordWithNumber(string sentence, bool expectedResult)
    {
        string pattern = @"\b[example|demo|demonstration|test|testing]+\d*\b";
        var re = new Regex(pattern, RegexOptions.IgnoreCase);
        re.Match(sentence).Success.ShouldBe(expectedResult);
    }

这是测试运行结果的屏幕截图，显示 "Some Company" 和 "Some Company123" 失败：

然而，当我尝试使用 regex101.com 进行相同操作时，它正确地显示输入与正则表达式不匹配，如下两个屏幕截图所示：

为什么这在我的 .NetCore3.1 运行时间失败了？

@Thefourthbird 回答正确

[Theory]
[InlineData("Some Demo543 Company", true)]
[InlineData("Some Company", false)] 
[InlineData("Some Company123", false)] 
[InlineData("Some Test123 Company", true)]
[InlineData("Some Testing123 Company", true)]
[InlineData("Some Example123 Company", true)]
[InlineData("Some Demonstration321 Company", true)]
[InlineData("demo123", true)]
[InlineData("Testing123", true)]
[InlineData("Company123", false)]
[InlineData("Company", false)]
public void TestRegexSentenceContainsWholeWordWithNumber(string sentence, bool expectedResult)
{
    const string pattern = @"\b(?:example|demo|demonstration|test|testing)\d*\b";
    var re = new Regex(pattern, RegexOptions.IgnoreCase);
    Assert.Equal(expectedResult,  re.Match(sentence).Success);
}
