Wow, this is bad.  Instead we should use a struct:

MediaValuesArgs args;
args.viewportWidth = 500;
args.viewportHeight = 500;
args.deviceWidth = 500;

or maybe just MediaValues itself should be a struct?

+        500, // Viewport Width
+        500, // Viewport height
+        500, // Device Width
+        500, // Device Height
+        2.0, // Device pixel ratio
+        24, // Color bits per component
+        0, // Monochrome bits per component
+        MediaValues::MousePointer, // Pointer device
+        16, // Default font size
+        true, // 3D enabled
+        false, // scan media type
+        true, // screen media type
+        false, // print media type
+        true // Strict mode
+        );
+
+    for (unsigned i = 0; testCases[i].input; ++i) {
+        int effectiveSize = SizesAttributeParser::findEffectiveSize(testCases[i].input, mediaValues);
+        ASSERT_EQ(testCases[i].output, effectiveSize);
+    }
+}
