  • Method Details

    • json

      public static JsonUnitResultMatchers json()
      Creates JsonUnitResultMatchers to be used for JSON assertions.

    • node

      @NotNull public JsonUnitResultMatchers node(String newPath)
      Creates a matcher object that only compares given node. The path is denoted by JSON path, for example.

      this.mockMvc.perform(get("/sample").accept(MediaType.APPLICATION_JSON)).andExpect(json().node("root.test[0]").isEqualTo("1"));

      Parameters:
      newPath -
      Returns:
      object comparing only node given by path.

    • ignoring

      @NotNull public JsonUnitResultMatchers ignoring(@NotNull @NotNull String ignorePlaceholder)
      Sets the placeholder that can be used to ignore values. The default value is ${json-unit.ignore}

    • withTolerance

      @NotNull public JsonUnitResultMatchers withTolerance(double tolerance)
      Sets the tolerance for floating number comparison. If set to null, requires exact match of the values. For example, if set to 0.01, ignores all differences lower than 0.01, so 1 and 0.9999 are considered equal.

    • withTolerance

      @NotNull public JsonUnitResultMatchers withTolerance(@Nullable @Nullable BigDecimal tolerance)
      Sets the tolerance for floating number comparison. If set to null, requires exact match of the values. For example, if set to 0.01, ignores all differences lower than 0.01, so 1 and 0.9999 are considered equal.

    • withDifferenceListener

      @NotNull public JsonUnitResultMatchers withDifferenceListener(@NotNull @NotNull net.javacrumbs.jsonunit.core.listener.DifferenceListener differenceListener)

    • when

      @NotNull public JsonUnitResultMatchers when(@NotNull @NotNull net.javacrumbs.jsonunit.core.Option firstOption, @NotNull @NotNull net.javacrumbs.jsonunit.core.Option... otherOptions)
      Sets options changing comparison behavior. For more details see Option

    • isEqualTo

      @NotNull public org.springframework.test.web.servlet.ResultMatcher isEqualTo(@Nullable @Nullable Object expected)
      Compares JSON for equality. The expected object is converted to JSON before comparison. Ignores order of sibling nodes and whitespaces.

      Please note that if you pass a String, it's parsed as JSON which can lead to an unexpected behavior. If you pass in "1" it is parsed as a JSON containing integer 1. If you compare it with a string it fails due to a different type. If you want to pass in real string you have to quote it "\"1\"" or use isStringEqualTo(String).

      If the string parameter is not a valid JSON, it is quoted automatically.

      Parameters:
      expected -
      Returns:
      this object.

    • isStringEqualTo

      @NotNull public org.springframework.test.web.servlet.ResultMatcher isStringEqualTo(@Nullable @Nullable String expected)

    • isNotEqualTo

      @NotNull public org.springframework.test.web.servlet.ResultMatcher isNotEqualTo(@Nullable @Nullable Object expected)
      Fails if compared documents are equal. The expected object is converted to JSON before comparison. Ignores order of sibling nodes and whitespaces.

    • isAbsent

      @NotNull public org.springframework.test.web.servlet.ResultMatcher isAbsent()
      Fails if the node exists.

      • Numbers are mapped to BigDecimal
      • Arrays are mapped to a Collection
      • Objects are mapped to a map so you can use json(Part)Equals or a Map matcher
      Parameters:
      matcher -
      Returns:

    • isTrue

      @NotNull public org.springframework.test.web.servlet.ResultMatcher isTrue()
      Fails if selected JSON is not true.

    • isFalse

      @NotNull public org.springframework.test.web.servlet.ResultMatcher isFalse()
