The test statistic in a hypothesis test for a population proportion is the z-value calculated from the sample. This is because we standardize the sample proportion using the expected standard deviation, which is calculated using the null hypothesis proportion. Thus, the resulting z-value represents how many standard deviations the sample proportion is from the null hypothesis proportion.
