类org.junit.platform.commons.util.Preconditions源码实例Demo

下面列出了怎么用org.junit.platform.commons.util.Preconditions的API类实例代码及写法,或者点击链接到github查看源代码。

private ConditionEvaluationResult map(EnabledIfProperty annotation) {
    final String name = annotation.named().trim();

    Preconditions.notBlank(regex, () -> "The 'matches' attribute must not be blank in " + annotation);

    return ConfigProviderResolver.instance().getConfig().getOptionalValue(name, String.class)
            .map(actual -> {
                return actual.matches(regex)
                        ? enabled(
                                format("Config property [%s] with value [%s] matches regular expression [%s]",
