I don't think this is a RenderGrid testing, we only test RenderStyle, which
happens to be on a RenderGrid.

That's why I think this would be better in the css/ directly. Thus we could test
non-grid renderers.

+class RenderGridTest : public testing::Test {
+protected:
+    virtual void SetUp() OVERRIDE
+    {
+        m_pageHolder = DummyPageHolder::create(IntSize(800, 600));
+
+        // This ensures that the minimal DOM tree gets attached
+        // correctly for tests that don't call setBodyInnerHTML.
+        document().view()->updateLayoutAndStyleIfNeededRecursive();
+    }
+
+    Document& document() const { return m_pageHolder->document(); }
+    RenderView& renderView() const { return *document().renderView(); }
+
+    void setBodyInnerHTML(const char*);
+
+private:
+    OwnPtr<DummyPageHolder> m_pageHolder;
+};
+
+void RenderGridTest::setBodyInnerHTML(const char* htmlContent)
+{
+    document().body()->setInnerHTML(String::fromUTF8(htmlContent), ASSERT_NO_EXCEPTION);
+    document().view()->updateLayoutAndStyleIfNeededRecursive();
+}
+
+TEST_F(RenderGridTest, JustifyItemsResolvedAutoValue)
+{
+    setBodyInnerHTML("<div style='display: grid; justify-items: auto'></div>");
+    RenderObject* renderer = document().body()->firstChild()->renderer();
+    EXPECT_EQ(renderer->isRenderGrid(), true);
+    EXPECT_EQ(ItemPositionStretch, renderer->style()->justifyItems());
+    EXPECT_EQ(OverflowAlignmentDefault, renderer->style()->justifyItemsOverflowAlignment());
+    EXPECT_EQ(NonLegacyPosition, renderer->style()->justifyItemsPositionType());
+}
+
+TEST_F(RenderGridTest, JustifySelfResolvedAutoValue)
+{
+    setBodyInnerHTML("<div style='display: grid; justify-items: right safe'><div style='display: grid; justify-self: auto'></div></div>");
+    RenderObject* container = document().body()->firstChild()->renderer();
+    RenderObject* renderer = toRenderBlock(container)->firstChild();
+    EXPECT_EQ(container->isRenderGrid(), true);
+    EXPECT_EQ(renderer->isRenderGrid(), true);
+    EXPECT_EQ(ItemPositionRight, renderer->style()->justifySelf());
