remove this?

[tudalex(Chromium), 2012/08/16 01:08:57]

No. It checks if the spaces we're removed correctly from the key. I know this is
covered also by the next line, but it is easier to realize what happened if they
both fail.

[satorux1, 2012/08/16 10:50:57]

ah that makes sense.

+  EXPECT_EQ("value2", response["key2"]);

[satorux1, 2012/08/15 22:01:09]

might want to add some comment:

// Make sure extra white space is removed.

[tudalex(Chromium), 2012/08/16 01:08:57]

Done.

[satorux1, 2012/08/15 22:01:09]

you can do:

EXPECT_EQ(0U, response.count("key3"));

+
+TEST(LSBReleaseLogSource, UTF8) {

[satorux1, 2012/08/15 22:01:09]

BrokenUTF8

[tudalex(Chromium), 2012/08/16 01:08:57]

Done.

+  std::string data("key=value\nkey2=\nkey3=");

[satorux1, 2012/08/15 22:01:09]

you could do "key=value\nkey2=\nkey3=\xFC" and remove the next line

[tudalex(Chromium), 2012/08/16 01:08:57]

Done.

+  data.push_back(253);

+  LsbReleaseLogSource::ParseLSBRelease(data, &response);
+  EXPECT_EQ("<invalid characters in log entry>", response["key3"]);

[satorux1, 2012/08/15 22:01:09]

you might also want to test with an empty string.

[tudalex(Chromium), 2012/08/16 01:08:57]

Done.
