我无法让 doctest
处理包含多行且开头可能包含空行的结果。这可能是由缩进和解析问题引起的。我找到了一些解决方案:
- 将想要的结果写入文件,
doctest
将结果与文件内容进行比较。 - 将结果的散列值与已知散列值进行比较。这种方法的主要缺点是,
doctest
的读者对期望的结果知之甚少。 - 找到一种使 doctest 处理多行结果的方法。
- 使用
unittest
代替doctest
。
有什么想法吗?
代码:
>>> data_lists=[ {"Average execution" : [1, 2, 3, 2, 3]},
... {"Top execution" : [3, 4, 5, 7, 8, 11, 6]},
... {"Current execution" : [1, 2, 1, 2, 1, 5]} ]
>>> c=Chart(data_lists,
... ("Large<br>rooster", "Rsync rooster", "Pool<br>Chicken", "Disease"),
... width=700, height=300)
>>> print c.html.strip()
<div id="placeholder3" style="width:700px;height:300px"></div>
<script id="source" language="javascript" type="text/javascript">
$(function () {
var d0 = [[0, 1], [4, 2], [8, 3], [12, 2], [16, 3]];
var d1 = [[1, 3], [5, 4], [9, 5], [13, 7], [17, 8], [21, 11], [25, 6]];
var d2 = [[2, 1], [6, 2], [10, 1], [14, 2], [18, 1], [22, 5]];
$.plot($("#placeholder3"), [
{ label: "Average execution", data: d0, bars: { show: true } },
{ label: "Top execution", data: d1, bars: { show: true } },
{ label: "Current execution", data: d2, bars: { show: true } }
],
{
xaxis: { ticks: [[1.5, "Large<br>rooster"], [5.5, "Rsync<br>rooster"], [9.5, "Pool<br>Chicken"], [13.5, "Disease"]] }
}
);
});
</script>

最佳答案
放<BLANKLINE>
在预期的输出中就像它在错误消息中显示的那样。然后测试应该可以正常工作。预期的输入终止于第一个只有空白的行,这就是为什么你必须特别标记它:
>>> data_lists=[ {"Average execution" : [1, 2, 3, 2, 3]},
... {"Top execution" : [3, 4, 5, 7, 8, 11, 6]},
... {"Current execution" : [1, 2, 1, 2, 1, 5]} ]
>>> c=Chart(data_lists,
... ("Large<br>rooster", "Rsync rooster", "Pool<br>Chicken", "Disease"),
... width=700, height=300)
>>> print c.html.strip()
<div id="placeholder3" style="width:700px;height:300px"></div>
<BLANKLINE>
<script id="source" language="javascript" type="text/javascript">
$(function () {
<BLANKLINE>
var d0 = [[0, 1], [4, 2], [8, 3], [12, 2], [16, 3]];
var d1 = [[1, 3], [5, 4], [9, 5], [13, 7], [17, 8], [21, 11], [25, 6]];
var d2 = [[2, 1], [6, 2], [10, 1], [14, 2], [18, 1], [22, 5]];

$.plot($("#placeholder3"), [
