Computer Information: Re: Unit testing - self.assertEqual("Break it!", resp.content)

Hi,
I have been using assertEqual lately in my unit testing to deliberately make coverage break. By comparing <h2>Something False</h2> with the complete HTML returned (resp.content).

self.assertEqual("<h2>Something False</h2>", resp.content)

In order to reveal and debug these 3 links.

    self.assertNotContains(resp, '<a href="/admin/doc/">Documentation</a>')
    self.assertNotContains(resp, '<a href="/admin/password_change/">Change password</a>')
    self.assertNotContains(resp, '<a href="/admin/logout/">Log out</a>')

But the unit test debug output of the complete HTML returned doesn't reveal those 3 links. Why is that?

Compared to the HTML returned that I can see by manually checking the source page from my browser.

<div id="user-tools"> Welcome, <strong>joe</strong>.
<a href="/admin/doc/">Documentation</a> /
<a href="/admin/password_change/">Change password</a> /
<a href="/admin/logout/">Log out</a>
</div>

Is there something wrong with my overridden template file? Where I have removed {% block userlinks %} in order to reveal Django admins above 3 default links.

{% extends "admin/base_site.html" %}
{% load i18n %}

{% comment %}
{% block userlinks %}
{% trans "Change password" %} / <a href="/accounts/logout/">{% trans "Log out" %}</a>
{% endblock %}
{% endcomment %}

{% comment %}
{% block breadcrumbs %}
<div class="breadcrumbs">
<a href="{% url 'navi_polls:index' %}">{% trans "Home" %}</a>
&rsaquo; {% trans "Password reset" %}
</div>
{% endblock %}
{% endcomment %}

{% block title %}{% trans "Password reset - v.2" %}{% endblock %}

{% block content %}
<h1>{% trans "Password reset" %}</h1>
<p>{% trans "Forgotten your password? Enter your email address below, and we'll email instructions for setting a new one." %}</p>

<form action="" method="post">{% csrf_token %}
{{ form.email.errors }}
<p><label for="id_email">{% trans "Email address:" %}</label> {{ form.email }} <input type="submit" value="{% trans 'Reset my password' %}" /></p>
</form>
{% endblock %}

Hi,

You are trying to compare <h2> break it!<h2> with the complete HTML returned. Instead of assertEqual, use assertIn.

self.assertIn("<h2>Break it!</h2>", resp.content)

When I run this unit test to make it break so it can output a bunch of html data.

    self.assertEqual("<h2>Break it!</h2>", resp.content)

test.py
# Reset password no login

def test_Reset_no_login(self):
    self.assertTrue(isinstance(self.user, User))
    login = self.client.login(username='captain', password='america')

    self.assertEqual("<h2>Profile</h2>", resp.content)

    self.assertNotContains(resp, '<a href="/admin/doc/">Documentation</a>')
    self.assertNotContains(resp, '<a href="/admin/password_change/">Change password</a>')
    self.assertNotContains(resp, '<a href="/admin/logout/">Log out</a>')

Then I can't find these html tags in unit test's resp.content but when I manually check the html source page from the web browser then I see those 3 html tags.
Why isn't unit test resp.content output displaying these 3 html lines?
